The list below shows the names of students and the number of merits each student received during the school year:
James received 20 merits
Ann received 45 merits
Alex received 37 merits
Jennifer received 56 merits
Aidan received 27 merits
What was the mean number of merits received?
a. 37
b. 25
c. 43
d. 57
Answer : a
Explanation:
The mean value of any set of numbers indicates the average of those numbers. The average of the numbers is calculated by adding all the numbers and dividing them by how many times they occurred. For this example it will be as follows:
20 + 45 + 37 + 56 + 27 = 185
185 / 5 = 37
