Question

A random sample of employees is asked to rate the performance of a president. This president is fired and a new president is hired. After six months, another random sample of employees is asked to rate the performance of the new president. A rating of 1 corresponds to the worst performance, and 10 to the best possible performance. The ratings are shown below in Exhibit 2.89.
Create an appropriate graphical display for these data. Comment on similarities or differences in the ratings of the two presidents.
