The diagram below represent
Antwortdetails
The diagram you are referring to represents the Circular Flow of Income. This is a crucial concept in economics that demonstrates how money moves within an economy between different sectors. Let me explain it further in a simple and clear manner.
The Circular Flow of Income exhibits the interactions and transactions that occur between two major groups in an economy: the households and the firms. It is important to note that:
The flow of economic resources and money can be explained in two key types:
In an expanded model of the circular flow, other components may be included, such as the government, financial sector, and foreign markets, which illustrate additional flows such as taxes, government spending, savings, investments, and exports/imports.
Overall, the Circular Flow of Income provides a fundamental understanding of how economic activity is interconnected and how different sectors interact with one another in a continuous cycle.
Frage 2 Bericht
Producers operating in a free market economy are more efficient as a result of
Antwortdetails
In a free market economy, multiple producers are allowed to enter the market and compete with each other. This competition creates incentives for producers to become more efficient in order to gain a competitive advantage. When producers compete, they strive to offer better quality products, lower prices, and improved customer service. To achieve these goals, they need to find ways to reduce costs, increase productivity, and innovate. The pressure of competition encourages producers to constantly improve their efficiency to attract customers and maximize profits

In income determination theory, acceleration principles shows that
Antwortdetails
In income determination theory, the acceleration principle suggests that investment is the primary driver or cause, whil income is the resulting effect. The acceleration principle states that changes in investment levels lead to amplified or accelerated changes in income.
The acceleration principle posits that changes in investment levels have a multiplier effect on income. When investment increases, it leads to increased production, employment, and income generation.
Frage 4 Bericht
At the equilibrium price,
Antwortdetails
The equilibrium price in economics is a fundamental concept where the market operates most efficiently. To understand it fully, consider the following explanation:
When demand equates supply, it indicates the price at which the quantity of goods consumers are willing to buy (demand) is exactly equal to the quantity of goods producers are willing to sell (supply). This is the point where the market reaches equilibrium. At this price, there is no excess supply or demand, meaning that resources are being used most effectively, and there is no pressure on the price to change.
In contrast:
Thus, at equilibrium price, demand equates supply, ensuring the market operates smoothly without surplus or shortage.
Frage 5 Bericht
In the event of bankruptcy, owners of joint-stock companies lose
Antwortdetails
When a joint-stock company goes bankrupt, the owners or shareholders of the company only lose the capital they invested in that company. This is because joint-stock companies have a feature known as **limited liability**.
Limited liability means that shareholders are only responsible for losses up to the amount of money they invested in purchasing shares of the company. Therefore, in a bankruptcy situation, they **lose only the capital invested**, and their personal or private assets (like cars, houses, or bank accounts) are protected and not at risk. They are not liable beyond their shareholding, hence they do not lose their private properties or any future dividends they were expecting.
This feature of limited liability is very important as it encourages people to invest in joint-stock companies without the fear of losing their personal wealth.
Frage 6 Bericht
An economy in which decision of what to produce is taken partly by private individuals and state is referred to as Economy.
Antwortdetails
An economy in which decisions about what to produce are taken partly by private individuals and partly by the state is referred to as a Mixed Economy.
In a Mixed Economy, there is a combination of both private sector and public sector involvement. This structure allows private individuals to own businesses and make decisions about what to produce based on market demands and profitability. At the same time, the government also plays a significant role in economic decision-making, often by regulating certain industries or directly providing goods and services. The balance between these two forces aims to combine the benefits of both market dynamism and government oversight.
Here's a brief explanation of other economic systems to provide contrast:
In summary, a Mixed Economy represents a blend that includes elements of both market-driven and government-directed decisions, which sets it apart from other economic types.
Frage 7 Bericht
Which of the following NOT among the objectives of OPEC?
Antwortdetails
When analyzing the objectives of OPEC (Organization of the Petroleum Exporting Countries), it is important to look at the core goals that this organization typically aligns with:
1. To stabilize the price of oil in the world market: This is indeed one of the primary objectives of OPEC. By coordinating the oil production levels among its members, OPEC strives to maintain oil price stability in the global market.
2. To stabilize the revenue from oil to producing countries: Another key objective of OPEC includes ensuring consistent and fair revenue for its oil-producing member countries. By influencing oil prices and production levels, OPEC helps in maintaining stable revenues for these nations.
3. To make sure that oil flows to all the consuming countries: Ensuring the continuous supply of oil to consuming countries is a goal aligned with OPEC's efforts to balance supply and demand for economic and energy stability worldwide.
4. To establish petroleum refineries in all member states: This is NOT among the objectives of OPEC. OPEC does not focus specifically on establishing petroleum refineries in all its member states. The organization's primary focus is on coordinating and unifying the petroleum policies among its member countries, not on the physical establishment of refineries.
Frage 8 Bericht
The largest component of national income in developing countries consist of
Antwortdetails
In developing countries, the largest component of national income typically consists of wages and salaries. This means that the income earned by individuals from their employment or labor work forms a significant part of the national income. Several reasons contribute to this:
In contrast, components like rent and profit tend to form a smaller component of national income in developing economies. While these components are important, they are usually not as predominant as wages and salaries due to the lesser commercialization and capital-intensive industries compared to developed countries.
Frage 9 Bericht
Which of the following is NOT a major role of OPEC in production, and marketing of petroleum?
Antwortdetails
Refining of petroleum products in member countries is NOT a major role of OPEC in the production and marketing of petroleum.
Let me explain why:
In summary, the main roles of OPEC include balancing oil production and prices and ensuring a steady supply, but they do not majorly focus on the refining of petroleum products.
Frage 10 Bericht
An industry operating in a perfect competitive market situation will maximum profit when
Antwortdetails
In a perfectly competitive market, an industry or firm will maximize its profit when its Marginal Cost (MC) equals Marginal Revenue (MR). This is a fundamental principle of microeconomics that ensures the firm's resources are being used most efficiently.
Here's why:
If MC = MR, the cost of producing an additional unit is exactly equal to the revenue it generates, meaning any increase or decrease in production would not improve profitability. At this point, the firm is efficiently allocating its resources.
If MC < MR; it means that the cost of producing an extra unit is less than the revenue it brings. The firm can increase its profit by producing and selling more units.
Conversely, if MC > MR; the cost of producing an extra unit exceeds the revenue it brings, and the firm should reduce production to avoid losses.
Therefore, to achieve maximum profit, a firm in a perfectly competitive market should continue adjusting its output until the cost of the last unit produced is exactly equal to the revenue it produces, which occurs at MC = MR.
Frage 11 Bericht
Persistent fall In the general price level is known as
Antwortdetails
A persistent fall in the general price level is known as deflation.
To understand this better, let's break it down:
Hence, when we say "persistent fall in the general price level," we are accurately describing deflation.
Frage 12 Bericht
A market situation with few sellers and many buyers is called
Antwortdetails
The market situation you are referring to is called an oligopoly.
To put it simply, an oligopoly is a market structure where there are only a few sellers, or producers, who dominate the market, while there are many buyers. This creates a situation where the few sellers have significant control over the prices and market dynamics.
This structure is different from a perfect competition, where there are many sellers and buyers, with no single seller having significant market power. It is also different from a duopoly, which specifically refers to exactly two sellers.
The presence of a small number of sellers in an oligopoly leads to competitive strategies where the actions of one seller can influence the actions of others. This often results in strategic collaboration or competition, which affects prices and product offerings.
Frage 13 Bericht
If two bags of rice were sold for #1,250 a month ago and two weeks later, the same amount was used to procure one bag. This simply means that the value of money is
Antwortdetails
In this scenario, the price of rice has increased relative to the amount of money (N1,250) that could be used to purchase it. Initially, N1,250 could buy two bags of rice, but after two weeks, the same amount can only buy one bag.
This decrease in purchasing power demonstrates that the value of money has declined. In other words, the same amount of money can now buy fewer goods or services than before. This situation is often referred to as inflation, where the general price level of goods and services rises over time, reducing the purchasing power of money.
Frage 14 Bericht

Antwortdetails
The United Nations Conference on Trade and Development (UNCTAD) is a UN body that focuses on trade and development issues, particularly those affecting developing countries. One of the functions of UNCTAD is to facilitate the transfer of technology from developed to less developed countries. This involves promoting the dissemination and adoption of technology in less developed countries to enhance their productive capacities, economic growth, and development.
UNCTAD recognizes that technology plays a crucial role in bridging the development gap between countries. By facilitating the transfer of technology, UNCTAD aims to enable developing countries to access and utilize advanced knowledge, skills, and technological innovations available in developed countries. This transfer of technology can occur through various means such as technical assistance, capacity building, knowledge sharing, and promoting partnerships between developed and developing countries.
Frage 15 Bericht
Antwortdetails
The concept we are discussing here is the Price Elasticity of Demand (PED). It measures how much the quantity demanded of a commodity changes with a change in its price. The formula for calculating the price elasticity of demand is:
PED = (% Change in Quantity Demanded) / (% Change in Price)
First, we calculate the percentage change in quantity demanded:
Percentage change in quantity demanded:
= (Change in quantity demanded / Initial quantity demanded) × 100
= (-20 / 100) × 100 = -20%
Next, calculate the percentage change in price:
Percentage change in price:
= (Change in price / Initial price) × 100
= (2 / 8) × 100 = 25%
Now, we can substitute these values into the formula for PED:
PED = (% Change in Quantity Demanded) / (% Change in Price)
= (-20%) / (25%)
= -0.8
The price elasticity of demand is -0.8. The negative sign indicates that there is an inverse relationship between price and quantity demanded, which is normal for most goods. This value rounded to the nearest value provided in your options is 0.8. This implies it is inelastic demand, meaning the quantity demanded is not very responsive to price changes.
Frage 16 Bericht
When the total product starts falling, then the marginal product is
Antwortdetails
In the context of production, the Total Product (TP) refers to the total quantity of output produced by a firm. The Marginal Product (MP) is the additional output obtained by employing one more unit of a specific input, while keeping all other inputs constant.
When the Total Product starts to fall, it indicates that each additional unit of input is contributing less and less to the total output, to the extent that the output is actually decreasing. This means that any added input is no longer producing additional output but instead reducing it. Therefore, the Marginal Product in this situation is actually negative.
Here is why:
Frage 17 Bericht
The diagram belwo, shows the relationship between
Antwortdetails
The relationship shown in the diagram is most likely related to the **wage rate and unemployment.** Let me explain this relationship clearly:
The **wage rate** refers to the payment workers receive for their labor, typically expressed on an hourly, daily, or yearly basis. The **unemployment rate** is the percentage of the labor force that is jobless and actively looking for work.
When the **wage rate** offered in the market is above the equilibrium wage (where the supply of labor equals the demand for labor), firms may choose to hire fewer workers as it becomes more expensive to employ labor. This can lead to an **increase in unemployment**. Conversely, if the wage rate is lower, firms are more likely to hire additional workers, possibly decreasing unemployment.
Understanding this relationship is crucial in comprehending how wage policies can influence employment levels. Wage increases that are not aligned with productivity may result in higher costs for employers, potentially resulting in a reduction of jobs available, hence increasing unemployment. Therefore, there is a delicate balance between setting wage levels and maintaining employment levels in the economy.
Frage 18 Bericht
The following can be used to improve a country's balance of payment EXCEPT
Antwortdetails
The balance of payments is a record of all financial transactions made between consumers, businesses, and the government in one country with others. It includes trade in goods and services, investments, and money transfers. To improve a country's balance of payments, particularly the trade balance, countries may implement certain policies.
Anti-dumping policies are used to prevent foreign companies from selling goods at a price lower than their market value to gain an unfair advantage. By implementing anti-dumping policies, a country can protect its domestic industries from unfair competition, which can help improve the balance of payments by reducing imports or encouraging domestic consumption.
Granting subsidies to export producers can help improve the balance of payments by making domestic products cheaper and more competitive in international markets. By lowering production costs, subsidies can help increase exports, leading to an improvement in the balance of payments.
Increasing import duties is another way to improve the balance of payments. By imposing higher taxes on imported goods, a country can discourage imports and encourage consumers to purchase domestically produced goods. This can improve the trade balance by reducing the outflow of money used to purchase foreign products.
On the other hand, decreasing taxation on personal income doesn't directly affect the balance of payments. Reducing personal income tax may increase disposable income for consumers, which could lead to more consumption. However, this increased consumption might not necessarily focus on domestic goods, and could instead lead to higher imports. Therefore, among the options listed, decreasing taxation on personal income is the one least likely to directly improve a country's balance of payments.
Frage 19 Bericht
The demand for factors of production is said to be
Antwortdetails
In economics, the demand for factors of production is best described as being derived. What this means is that the demand for these factors, like labor, land, and capital, is not for their own sake but because of the demand for the goods and services they can produce.
To put it simply, businesses need these factors of production to create products. If there is a high demand for a particular product, there will naturally be a higher demand for the factors needed to produce that product. Conversely, if there is little to no demand for a product, then the demand for the factors required to produce it will also decrease.
For example, if there is a high demand for cars, a car manufacturing company will need more metal, labor, and machinery, which are the factors of production, to make more cars. Thus, the demand for these factors is based on, or derived from, the demand for the cars themselves.
Frage 20 Bericht
Economics problems arise in all societies because
Antwortdetails
Economics problems arise in all societies primarily because resources are not in adequate supply. This is known as the fundamental economic problem of scarcity. In every society, there are limited resources but unlimited wants and needs. These resources include things like land, labor, and capital, which are necessary for producing goods and services. Since we do not have enough of these resources to satisfy everyone's desires, we face choices about how to allocate them efficiently.
The issue of scarcity leads to other economic problems such as deciding what to produce, how to produce it, and for whom it should be produced. These decisions are made by assessing opportunity costs and considering how to make the best possible use of the limited resources available.
While factors such as lack of proper planning or mismanagement by leaders can exacerbate economic problems, they are not the root cause. The core issue remains the limited availability of resources, compelling societies to prioritize and decide how best to meet the needs of their population.
Frage 21 Bericht
The act of cultivating land and rearing of animal for man's use is
Antwortdetails
The act of cultivating land and rearing of animals for man's use is known as agriculture.
Agriculture is an activity that involves growing crops and raising animals to provide food, fiber, medicinal plants, and other products used to sustain and enhance human life. It is a vital practice that has been developed over thousands of years, allowing civilizations to flourish by ensuring a stable supply of food and resources. This practice not only involves the cultivation of the land for crops but also includes various other activities such as animal husbandry, which is the breeding and care of farm animals.
Let me explain a bit about the other terms you mentioned:
Thus, the most comprehensive term that covers both the cultivation of land and rearing of animals is agriculture.
Frage 22 Bericht
A firm's average cost decreases in the long-run because of
Antwortdetails
In the long run, a firm's average cost decreases primarily because of increasing returns to scale. This occurs when a firm's output increases by a proportion greater than the increase in inputs. In simpler terms, when a company gets bigger, it becomes more efficient at production. Consider the following reasons:
Other options, like **diminishing average returns** or **decreasing marginal returns**, generally pertain to situations in the short run or under different conditions and would not directly explain a decrease in average costs in the long run. Additionally, while **decreasing average fixed cost** could reduce cost in the short run, in the long run, all costs are variable and focus instead shifts to how efficiently inputs are converted to outputs.

Frage 24 Bericht
The trade-off between two commodities along the Production Possibility Curve (PPC) shows
Antwortdetails
The Production Possibility Curve (PPC) is a graphical representation that shows the different combinations of two goods or services that an economy can produce, given certain assumptions like fixed resources and technology.
The trade-off between two commodities along the PPC primarily illustrates the opportunity cost principle. This principle refers to the idea that in order to produce more of one good, an economy must produce less of another good. The curve demonstrates this trade-off by showing that resources are limited, and choosing to allocate more resources to produce one commodity means reallocating those resources away from another commodity.
For example, if an economy is at a certain point on its PPC and decides to produce more of Commodity A, it will inevitably end up producing less of Commodity B. This reduction in the production of Commodity B is the opportunity cost of producing more of Commodity A. Hence, every point along the PPC illustrates the trade-off and opportunity cost of choosing different production levels of the two goods.
Frage 25 Bericht
The satisfaction derived from the consumption of a commodity is referred to as
Antwortdetails
The satisfaction derived from the consumption of a commodity is referred to as utility. To explain this concept further, let's break it down:
Utility is an economic term that describes the pleasure, happiness, or satisfaction a consumer gets from consuming goods and services.
Here’s why it is the correct term:
In summary, whenever we talk about the satisfaction from using or consuming goods, we are discussing the concept of utility.
Frage 26 Bericht
What is the median term in the distribution below; 14, 13 29,15,13,17,12.
Antwortdetails
To find the median of a set of numbers, the first step is to arrange the numbers in ascending order (from smallest to largest).
The given numbers are: 14, 13, 29, 15, 13, 17, 12.
Arrange them in ascending order: 12, 13, 13, 14, 15, 17, 29.
The median is the number that appears in the middle of this ordered list. Since there are 7 numbers in this list, the middle number is the fourth one.
In the ordered sequence 12, 13, 13, 14, 15, 17, 29, the median is 14.
Frage 27 Bericht
If the price of commodity X rises and consumers shift to commodity Y, then commodities X and Y are
Antwortdetails
If the price of commodity X increases and consumers start purchasing commodity Y instead, then commodities X and Y are considered substitutes. Substitutes are goods that can be used in place of one another; when the price of one goes up, consumers naturally shift their demand to the other because it serves a similar function or purpose.
Consider an example: if the price of coffee goes up, people might start drinking tea instead if tea serves as a similar alternative for their morning beverage needs. In this scenario, coffee and tea are substitutes. Therefore, the relationship between these goods is defined by consumers' ability to consider one in place of the other based on price.
In summary, when consumers replace their consumption of one good with another due to price change, the goods in question are substitutes.
Frage 28 Bericht
Which of the following is a disadvantage of localization of industries?
Antwortdetails
Localization of industries, also known as industrial clustering or agglomeration, refers to the concentration of similar industries or related businesses in a specific geographic area. While there are various advantages associated with localization, such as promoting knowledge spillovers, fostering collaboration, and enhancing economies of scale, it can also have disadvantages.
One of the disadvantages is the creation of structural unemployment. When industries concentrate in a particular region job opportunities may become limited to that specific area. As a result, workers in other regions or industries may face challenges in finding employment, leading to structural unemployment. This can be particularly problematic if the localized industry experiences a decline or faces disruptions, resulting in job losses for a significant portion of the workforce.
Frage 29 Bericht
An exceptional demand curve can result from
Antwortdetails
An exceptional demand curve occurs when demand does not follow the typical downward slope from left to right. Instead, the demand curve may slope upward. Let’s consider some scenarios that could lead to this unusual situation.
Increase in Price of Raw Materials: This typically affects the supply side rather than the demand side. When prices of raw materials increase, production costs go up, possibly reducing supply, but not necessarily impacting demand directly. Therefore, this is not usually a reason for an exceptional demand curve.
Change in Taste of Consumer: If consumers suddenly prefer a particular product, they may be willing to buy more even if the price rises. This shift in consumer preferences can lead to an upward-sloping demand curve, reflecting increased demand despite higher prices.
Increase in the Size of the Population: More people can lead to higher overall demand, but each individual’s demand curve typically still slopes downward due to the law of diminishing marginal utility. Therefore, population increase alone generally does not cause an exceptional demand curve.
Expectation of Future Price Increase: When consumers expect prices to rise in the future, they may choose to buy more now to avoid paying higher prices later. This situation can lead to an upward-sloping demand curve as current demand increases with rising prices, due to future price expectations.
In summary, an exceptional demand curve is usually caused by changes in consumer tastes or expectations of future price increases, making current demand behave in an unexpected way compared to the usual downward slope.
Frage 30 Bericht
What add funds to the circular flow?
Antwortdetails
The concept of the circular flow of income represents how money moves within an economy among consumers, businesses, and various markets. In this circular flow, three key elements can either add to or reduce the flow of funds: **leakages** and **injections**.
Leakages are the flows of money that exit the circular flow. They reduce the amount of money that circulates within the economy. Common leakages include savings, taxes, and imports. For instance, when individuals save money instead of spending it, that money is not used to purchase goods or services, thus exiting the circular flow.
Injections, on the other hand, are the activities or financial inflows that add funds to the circular flow of income, ensuring continued economic activity. They increase the total amount of money circulating in the economy. These include investment, government spending, and exports.
The expenditure approach is a method for calculating a nation's Gross Domestic Product (GDP) by considering the total expenditure on the nation's final output of goods and services in a year. While this approach helps to measure the size of the economy, it is not directly responsible for adding funds to the circular flow. Instead, it relies on the activities of consumption, investment, government spending, and net exports.
In conclusion, it is the concept of injection that directly adds funds to the circular flow, stimulating economic activities and growth by multiplying the effects of initial spending through the economy.
Frage 31 Bericht
Which of these is NOT associated with the problem of internal trade?
Antwortdetails
Market trade unions are not typically associated with the problem of internal trade. Trade unions are typically formed b workers or employees to protect their rights, negotiate better working conditions, and advocate for their interests. While trade unions can have an impact on labor markets and industrial relations, they are not directly linked to the challenges or problems specifically related to internal trade.
Frage 32 Bericht
In the long-run, a firm must shut down if its average revenue is
Antwortdetails
In the long-run, a firm must shut down if its average revenue is less than its average variable cost. This is because the firm is unable to cover even its variable costs, which are the costs it incurs when it produces any output at all. Let me explain further:
To put it simply, if average revenue is less than average variable cost, the firm can't sustain itself in the long-run, and shutting down is a rational decision.
Frage 33 Bericht
A producer who can only influence the price of his product but canNOT determine the quantity to be sold is referred to
as
Antwortdetails
A producer who can influence the price of a product but cannot determine the quantity to be sold is best described as a monopolist.
Here's an explanation:
In a monopoly, there is only one producer or seller who dominates the entire market for a particular product or service. This producer has the power to influence the price because they are the sole supplier, and there are no close substitutes. However, while they can set the price based on their objectives, the actual quantity sold is determined by the market demand at that specific price.
The other terms are different:
Frage 34 Bericht
In the equation Q = a - bp + e; Q and P are ... Variables respectively.
Antwortdetails
In the given equation Q = a - bp + e, we need to understand the roles of the variables Q and P.
In any equation where we are trying to establish a relationship between two variables, one of the variables is usually controlled or changed deliberately, while the other one is observed as it changes in response. In such equations:
In the equation Q = a - bp + e, **Q** is the outcome or result that we observe, and it depends on the value of **P**. Thus, **Q is the dependent variable** because it changes depending on the values of **P**. Conversely, **P** is the one that we can change or manipulate in the context of this equation, so **P is the independent variable**.
Therefore, the correct description for **Q** and **P** is that Q is the **dependent** variable, and P is the **independent** variable.
Frage 35 Bericht
Stock exchange market deals with
Antwortdetails
The stock exchange market primarily deals with the sales of second-hand securities. In this context, "second-hand securities" refer to financial instruments such as stocks and bonds that have already been issued by a company and are currently being traded among investors. When a company first issues stocks or bonds, it is done in the primary market. Once these securities are purchased and then resold by investors, they are traded in the secondary market, commonly known as the stock exchange.
Here's a simple rundown of how it works:
1. **Initial Offering:** A company looking to raise capital might issue stocks or bonds to investors. This takes place in the primary market through an Initial Public Offering (IPO) or similar mechanisms.
2. **Secondary Trading:** Once issued, these securities can be bought and sold on the stock exchange. Investors trade these securities based on supply and demand, trying to make a profit by buying low and selling high.
Therefore, the stock exchange acts as a platform where buyers and sellers meet to trade these second-hand securities. This buying and selling provide the liquidity required for the market to function efficiently and helps in price discovery of the securities based on market demand.
Frage 36 Bericht
f the population of a school is 600 and 60% are In JSS, how many students are in SSS?
Antwortdetails
To determine how many students are in SSS, we first need to figure out how many students are in JSS. According to the problem, 60% of the school's population is in JSS.
Here's a simple breakdown:
Since the whole school has 600 students, and 360 of those are in JSS, we can find out how many are in SSS by subtracting the JSS students from the total number of students:
600 - 360 = 240
Hence, there are 240 students in SSS.
Frage 37 Bericht
The middle value of an array figure arranged in descending order is referred to as the
Antwortdetails
The middle value of an array of figures arranged in descending order is referred to as the median.
To understand this concept, imagine you have a collection of numbers, and you want to find the one that sits right in the middle when all numbers are lined up from the largest to the smallest (or even from smallest to largest, as the median remains the same).
The median is very useful as a measure of central tendency because it is not affected by extremely large or small values in the dataset, which could skew other measurements like the mean. Thus, it provides a better representation of a typical value within the dataset, especially when dealing with outliers.
Frage 38 Bericht
The formular (N + 1)/2 is used to determine the
Antwortdetails
The formula (N + 1)/2 is used to determine the median position in a dataset that is arranged in ascending or descending order. Understanding how to find the median is important because the median is a measure of central tendency that represents the middle value of a dataset. Here's a clear explanation of this concept:
When you have a set of numbers, the median is the number that falls in the middle when the numbers are arranged in either increasing or decreasing order. To find this middle value, you can use the formula (N + 1)/2, where N represents the total number of observations in the dataset.
For example, let's say you have a dataset with an odd number of observations: 3, 5, 7. Here, N is 3, so you apply the formula:
Median position = (3 + 1)/2 = 2
This calculation indicates that the second number in this ordered list is the median, which is 5.
If you have an even number of observations, such as 2, 4, 6, 8, you would calculate the median position as follows:
Median position = (4 + 1)/2 = 2.5
In this case, because 2.5 isn't an integer, the median is the average of the second and third numbers, which are 4 and 6. Therefore, the median is (4 + 6)/2 = 5.
In summary, the formula (N + 1)/2 is used to identify the position of the median in a list of numbers that are ordered, allowing us to understand where the middle point of the data lies.
Frage 39 Bericht
The willingness of an individual backed up with purchasing power at a given time is
Antwortdetails
The concept you are referring to is effective demand. Let me explain it to you in a straightforward way:
Demand: Generally, demand refers to the desire or willingness of a consumer to purchase goods or services. However, just having the desire is not enough. Demand becomes impactful only when it is supported with the capability to purchase.
Effective demand: This is more than just a simple desire or demand. It represents the situation where an individual not only wants to purchase a product or service but also has the actual purchasing power to do so. This means they have the money or resources to back up their desire at a given time.
Desire: This term simply denotes a wish or want, without any implication of capability to fulfill it. For instance, many people might desire a luxury car, but not everyone can afford it.
Utility: This is a different concept entirely, referring to the satisfaction or benefit a consumer receives from consuming a product or service. It does not necessarily align with the ability to purchase.
In summary, when discussing the willingness to buy something and having the funds ready at that moment, it's referred to as effective demand because it combines the desire with the actual capacity to fulfill that desire.
Frage 40 Bericht
The revolution of Cassava from ordinary food crop to export crop will lead to
Antwortdetails
The recent revolution of cassava from an ordinary food crop to an export crop is likely to lead to an increase in the price of cassava products.
When cassava transitions from being primarily used as a food crop to an export crop, its demand and value in the international market tend to increase. This increased demand can result in higher prices for cassava products such as cassava flour, starch, or other processed derivatives.
