1. Since the data involve two variables and a third labeling variable, enter the data into the first three columns of a MINITAB worksheet, using the labels in the table. Using the drop-down menus, select Stat ➤ Basic Statistics ➤ Display Descriptive Statistics. The Dialog box is shown in Figure 2.20(a).

2. Now click on the Variables box and select both columns from the list on the left. (You can click on the Graphs option and choose one of several graphs if you like. You may also click on the Statistics option to select the statistics you would like to see displayed.) Click OK.
A display of descriptive statistics for both columns will appear in the Session window (see Figure 2.20(b)). You may print this output using File ➤ Print Session Window if you choose.
3. To examine the distribution of the two variables and look for outliers, you can create box plots using the command Graph ➤ Boxplot ➤ One Y ➤ Simple. Click OK. Select the appropriate column of measurements in the Dialog box (see Figure 2.21(a)). You can change the appearance of the box plot in several ways. Scale ➤ Axes and Ticks will allow you to transpose the axes and orient the box plot horizontally, when you check the box marked “Transpose value and category scales.” Multiple Graphs provides printing options for multiple box plots. Labels will let you annotate the graph with titles and footnotes. If you have entered data into the worksheet as a frequency distribution (values in one column, frequencies in another), the Data Options will allow the data to be read in that format. The box plot for the front leg rooms is shown in Figure 2.21(b).
4. Save this worksheet in a file called “Leg Room” before exiting MINITAB. We will use it again in Chapter 3.
