Walter’s history test scores and Janine’s history test scores are shown on the dot plots below.

Walter’s History Test Scores
A dot plot tilted Walter's History Test Scores. A number line going from 80 to 90. There are 0 dots above 80, 81, and 82, 1 above 83, 2 above 84, 2 above 85, 2 above 86, 2 above 87, 0 above 88 and 89, and 1 above 90.

Janine’s History Test Scores
A dot plot tilted Janine's History Test Scores. A number line going from 80 to 90. There are 0 dots above 80, 81, 82, and 83, 3 above 84, 2 above 85, 2 above 86, 3 above 87, and 0 above 88, 89, and 90.

If each student gets 65 on the next test, which explains the measure of center that would be most affected?
Their means will be most affected because this value will be an outlier.
Their modes will be most affected because the distribution has changed.
Janine’s median will be more affected than Walter’s median because her overall scores were greater.

Using the dot plot and statistical concepts, it is found that the correct option is:

The dot plot shows the number of times each measure appears in the data-set.

In this problem, for both Walter and Janine, the dot plots are cluster between 80 and 90, which means that their grades are in this range.

Hence, for both, a grade of 65 would be an outlier, and the measure that is most affected by outliers is the mean.

Hence, the correct option is:
