Answer:IBM or Compatible in beige color Explanation:As shown in the Crosstabulation matrix above,IBM or Compatible is the most preferred computer type from the row variable(Computer Owned).From the column variable (color),beige is shown as the most preferred color.Therefore,you can conclude that most people prefer IBM or Compatible computers that are in beige color. Data Manipulation Data files are not always ideally organized in a form to meet specific needs.For example,users may wish to select a specific subject or split the data file into separate groups for analysis Select Cases If you have two or more subject groups in your data and you want to analyze each subject in isolation,you can use the select cases option.For example,the data we are currently analyzing has both male and female participants.However,if you wish to analyze only female cases,then you select Gender cases and set the condition for female cases only. To select cases for analysis: 1.Click the Data menu and select Select Cases(see Figure 16).The Select Cases dialog box opens(see Figure 17). 2.Select the If condition is satisfied option. 3.Click the If button.The Select Cases:If dialog box opens. 4. Select the variable Gender in the left list box. 5. Click the transfer arrow button to move it to the right text box. 6.Click the button 7. Click the 1 button 8.Click the Continue button.This takes you back to the Select Cases dialog box 9.Click the OK button.This takes you back to Data View.All males will be excluded from the statistical analysis. 10.Rerun the crosstabs analysis by following steps 1 through 6 of the Crosstabs section of this handout. 11.Click the OK button.The Output Viewer window updates (see Figure 18).
