A demand schedule is a table showing the relationship between the price of a good and the quantity of that good that consumers are willing and able to buy. It lists the various prices of a good and the corresponding quantity demanded by consumers at each price. Essentially, it shows the demand curve for a particular product, which reflects the law of demand, stating that as the price of a good increases, the quantity demanded by consumers decreases, all other factors being equal. Therefore, a demand schedule is a useful tool for businesses to understand how changes in price affect the quantity of goods they can sell, and for economists to analyze consumer behavior and market trends.
