Occupational prestige is a statistic developed by sociologists to measure the status of one's occupation. Occupational prestige is also a component of what sociologists call socioeconomic status, a composite measure of one's status in society. On average, people with more education tend to have higher occupational prestige than people with less education. We investigate this using the 2010 GSS variable PRESTG80 and the Explore procedure to generate the selected SPSS output shown in Figure 5.15.

a. Note that SPSS supplies the IQR, the median, and the minimum and maximum values of each group. Looking at the values of the mean and median, do you think the distribution of prestige is skewed for respondents with a high school diploma? For respondents with a bachelor's degree? Why or why not?
b. Explain why you think there is more variability of prestige for either group, or why the variability of prestige is similar for the two groups.
