Exercise 13-2. Chapter 13 in the textbook discussed cross-tabulation as it relates to the analysis of two variables. Answer each of the following questions about why and how we might use a cross-tabulation for analysis. a . Cross-tabulations are for categorical data. What are categorical data? How would you define a categorical variable? b. Why would it be difficult if not impossible to use a cross-tabulation to examine two variables that capture continuous data rather than categorical data? c. When the categories of the independent variable are arrayed across the top of a cross-tabulation table, that is, they are the column labels. Why is it essential that the column percentages equal 100 d. For what purpose would you use gamma in analyzing data in a cross-tabulation? e. How would you interpret a gamma value? How would you interpret a gamma value of -1? f. How much magnitude (the distance from 0 ) would you want to see in gamma before concluding that there is a strong relationship between the variables?
