Textbook Question

Chapter 3, Problem 3.73CRP

You are planning to study for your statistics examination with a group of classmates, one of whom you particularly want to impress. This individual has volunteered to use Microsoft Excel to generate the needed summary information, tables, and charts for a data set that contains several numerical and categorical variables assigned by the instructor for study purposes. This person comes over to you with the printout and exclaims, “I’ve got it allâ€”the means, the medians, the standard deviations, the boxplots, the pie chartsâ€”for all our variables. The problem is, some of the output looks weirdâ€”like the boxplots for gender and for major and the pie charts for grade point average and for height. Also, I can’t understand why Professor Szabat said we can’t get the descriptive stats for some of the variables; I got them for everything! See, the mean for height is 68.23, the mean for grade point average is 2.76, the mean for gender is 1.50, the mean for major is 4.33.” What is your reply?
