Question 5.38

8. A survey of a large college class asked the following questions:

  • (i) Are you female or male? (In the data, male = 0, female = 1.)
  • (ii) Are you right-handed or left-handed? (In the data, right = 0, left = 1.)
  • (iii) What is your height in inches?
  • (iv) How many minutes do you study on a typical weeknight?

Figure 5.30 shows histograms of the student responses, in scrambled order and without scale markings. Which histogram goes with each variable? Explain your reasoning. Would the 0-1 coding scheme work for someone who is ambidextrous (or transgendered)?

Figure 5.32: Figure 5.30 For Exercise 8, match each histogram with its variable.

Table 5.13 lists the top 100 baseball players ranked by career batting average. (These data were collected after the completion of the 2014 season.) Exercises 9 and 10 require use of the data from Table 5.13. (You will revisit these data in Chapter 6, Exercise 60.)
