A single graph containing separate bar charts for different years would be nice here. This tells the conditional distribution of smoke cigarettes given gender, suggesting we are considering gender as an explanatory variable (i.e. In a cross-tabulation, the categories of one variable determine the rows of the table, and the categories of the other variable determine the columns. The next screenshot shows the first of the five tables created like so. One simple option is to ignore the order in the variable's categories and treat it as nominal.

Step 2: Run linear regression model Select Linear in SPSS for Interaction between Categorical and Continuous Variables in SPSS Drag write as Dependent, and drag Gender_dummy, socst, and Interaction in "Block 1 of 1". Since now we know the regression coefficients for both males and females from steps 2 and 3, we can add regression coefficients to the interaction plot. For example, if we had a categorical variable in which work-related stress was coded as low, medium or high, then comparing the means of the previous levels of the variable would make more sense.
