Answer:
Both the mean and the median
Step-by-step explanation:
Whichever measure, mean or median, is higher, Ari will benefit from that.
<u>Median:</u>
Median is the "middle value" of the list when arranged from least to greatest.
<em>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.</em>
Arranged from least to greatest: 73, 76, 80, 88, 90, 97
Average of 3rd and 4th is the Median = 
<u>Mean:</u>
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.
