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 the median both the mean and the median neither the mean nor the median

Both the mean and the median

Step-by-step explanation:

Whichever measure, mean or median, is higher, Ari will benefit from that.

Median:

Median is the "middle value" of the list when arranged from least to greatest.

Since there is 6 numbers, the middle number is between the 3rd and 4th number. Hence, we take the average of the 3rd and 4th number.

Arranged from least to greatest: 73, 76, 80, 88, 90, 97

Average of 3rd and 4th is the Median =

Mean:

Mean is the sum of all the number divided by the number of numbers (6).

So we have:

Mean =

Mean is 84

Since Mean and Median are both same (84%), both will be best measure of center for Ari.

answer: the answer is 127 degrees
