Question

The test score for a class are shown. What is the average test score? 79,80,92,92,81,100,88,98,71,100,91,90

Answer 1

The average score is equal to 88.5

Explanation:

we know that

An average test score is the sum of all the scores on an assessment divided by the number of test-takers.

so

The sum is equal to

`Sum=[79+80+92+92+81+100+88+98+71+100+91+90]=1,062`

The number of test-takers is n=12

The average score is equal to

`(S)/(n)`

substitute

`(1,062)/(12)=88.5`
