Using the dot plot and statistical concepts, it is found that the correct option is:
- Their means will be most affected because this value will be an outlier.
<h3>What is a dot plot?</h3>
- The dot plot shows the <u>number of times each measure appears in the data-set.</u>
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:
- Their means will be most affected because this value will be an outlier.
