Question

If you have the following test scores:90 , 78 ,66 ,90 ,54 , and 72 , what is your mean test score

Answer 1

Answer: 75

Explanation:

To find the mean, you find the sum of your numbers and divide by the amount of numbers you added.

90+78+66+90+54+72 = 450

You added 6 numbers, so you divide 450 by 6.

450/6 = 75

Answer 2

To calculate for the mean test score, we must take the sum of all the test scores divided by the number of tests. We can represent this by the equation:



Therefore, the mean test score is 79.
