Question

Ari’s teacher says he may have his report grade based on either the mean or the median of his last six test scores.

88%, 73%, 97%, 76%, 90%, 80%

Which measure of center would best represent Ari’s grade?

Answer 1

Mean because it is the average of all of them combined = best representation of all grades.

84% & Mean

Explanation:

88 + 73 + 97 + 76 + 90 + 80 = 504

**divide by how many grades there are** (6 of them)

504 / 6 = 84

Meaning the best center representation would be 84%

Answer 2

Answer: The Mean

The mean is when you add up all of those grades and divide by the amount of exams.
