The table above shows the distribution of marks scored by students in a test. How many candidates scored above the median score?
Answer Details
To find the median score, we need to arrange the scores in ascending or descending order. From the table, we can see that there are 40 candidates in total.
To determine the median score, we need to find the middle value. Since there are an even number of candidates (40), the median will be the average of the two middle values.
The two middle values are the 20th and 21st scores, which are both 3. Therefore, the median score is 3.
To find how many candidates scored above the median score, we can add up the number of candidates who scored 4 and 5, which are the scores above 3.
From the table, we can see that 9 candidates scored 4 and 3 candidates scored 5, making a total of 12 candidates who scored above the median score of 3.
Therefore, the answer is 12.
