Question

In her seventh grade pre-algebra class, Ms. Cornelius gave a standardized exam prepared by the district math department. Students' scores on the exam were as follows:

100, 98, 98, 96, 96, 96, 94, 92, 88, 82.
What is the mean score?

Answer 1

Answer: 94

Explanation:

The mean is the average of the numbers,

To find the mean add all the numbers and divide by how many numbers there are i.e count the numbers

In this case lets find the sum;

Sum = 100 + 98 + 98 +96 + 96 + 96 + 94 + 92 + 88 + 82

= 940

Count the numbers : There are 10 numbers in total.

Therefore, The mean = 940/10

= 94
