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?

The mean is 84%: (88 + 73 + 97 + 76 + 90 + 80) ÷ 6 = 504 ÷ 6. In order, the scores are 73%, 76%, 80%, 88%, 90%, and 97%, so the median is (80 + 88) ÷ 2 = 84%. Since the mean and median are equal, both represent Ari’s grade equally well; the correct choice is “both the mean and the median.”
