The data to represent average test scores for a class of 19 students includes an outlier value of 81. If the mean, including the outlier of 81, equals 94, which statement is always true about the new data when the outlier is removed?
A. The median would increase.
B. The median would decrease.
C. The mean would increase.
D. The mean would decrease.

Average is the mean of the data set obtained by summing all the values of the data set and then dividing it by the number of data in the set.

The total number of students is 19.

The outlier is 81

An outlier is a number that is different from the other set of numbers, it is obtained due to variability in the observation or due to experimental error.

The mean including the outlier of 81 equals 94.

For the mean including the outlier, it can be observed that the outlier is the left outlier or the smallest number.

Let x represent the sum of all the test scores

x / 19 = 94

x = 94 * 19

x = 1786

The sum without the outlier is 1786 - 81 = 1705

The mean without the outlier is

= 1705 / 18

= 94 13 /18

This is greater than 94.
