Question

Name that variable. A survey of a large college class asked the following questions:

1. Are you female or male? (In the data, male = 0, female = 1.)
2. Are you right-handed or left-handed? (In the data, right = 0, left = 1.)
3. What is your height in inches?
4. How many minutes do you study on a typical weeknight? Figure 1.17 shows histograms of the student responses, in scrambled order and without scale markings. Which graph goes with each variable? Explain your reasoning.

Answer 1

1. Are you female or male? (In the data, male = 0, female = 1.) for this question the bar chart is appropriate, because the response is measured on nominal sacle.
2. Are you right-handed or left-handed? (In the data, right = 0, left = 1.) for this question the bar chart is appropriate, because the response is measured on nominal sacle.
3. What is your height in inches? for this question the Histogram is appropriate, beacuse the reponses are measured on numerical scale also it is continuous.
4. How many minutes do you study on a typical weeknight? for this question the Histogram is appropriate, beacuse the reponses are measured on numerical scale also it is continuous.
