Answer:

Go with the mean and remove the lowest score

Explanation:

84%, 71%, 64%, 90%, 75%, 44%, 98%

First find the mean, which is add all the numbers and divide by the number of numbers

(84+ 71+ 64+ 90+ 75+ 44+98)/7

526/7 =75.14

If we drop one score, we would drop the lowest

(84+ 71+ 64+ 90+ 75+98)/6

482 /6 = 80.33

If we use the median, we take the middle, so put the scores from lowest to highest

44%, 64%,71%, 75%, 84%,90% , 98%

Without removing a score the median is 75%

Removing the lowest score

64%,71%, 75%, 84%,90% , 98%

The median is between 75 and 84

(75+84)/2 = 79.5 %
