Please explain how you can control the effects of a third variable in a multivariate cross-tabulation by grouping.
What will be an ideal response?
In a multivariate cross-tabulation, we control a third variable by holding it constant. In effect, we control by grouping, that is, we group the observations according to their values on the third variable and then observe the original relationship within each of these groups. In our example, each group consists of people with more or less the same income. If a relationship between opinions on spending and voting in these groups remains, it cannot be due to income.
