Cross-Tabulation is defined as?

• A. Comparing categories of one variable across categories of another variable.
• B. Calculating the mean of a variable.
• C. Plotting a histogram.
• D. Testing for normality.

Answer: (A)

Cross-tabulation is about examining how two categorical variables relate by comparing categories of one variable across categories of another. You lay out data in a contingency table, with one variable as rows and the other as columns, and fill in counts or percentages for each cell. This structure lets you see patterns—whether certain categories tend to occur together or if the variables appear independent—often prompting further tests like a chi-square. The other options describe different kinds of analysis: calculating a mean summarizes a numeric variable, plotting a histogram shows the distribution of a single variable, and testing for normality asks whether a variable’s distribution follows a normal curve. So cross-tabulation best matches the idea of comparing categories across two variables.
