Minitab was used to generate stem-and -leaf for the salaries of both the female and male researchers. See the Exhibits 1-3 for the following in the attached file.

(f) With reference to the box-and-whisker diagrams, compare the salaries of the
researchers selected in your sample, by gender. Ensure that you comment on
the skewness, the median, the interquartile range, the minimum and the
maximum values of both diagrams.

MINITAB was used to generate the descriptive statistics for all the 35 researchers selected in the sample. See Exhibit 3 below.
