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

Answer:

The average score is equal to 88.5

Step-by-step 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

$\frac{S}{n}$

substitute

$\frac{1,062}{12}=88.5$
