Name at least three circumstances in which it is appropriate to add a third variable into a cross-tabulation. Why would you do each? What features of the bivariate relationship could be demonstrated using a three-variable crosstab?
What will be an ideal response?
Three different uses for three-variable cross-tabulation: (1) identifying an intervening variable, (2) testing a relationship for spuriousness, and (3) specifying the conditions for a relationship; each type of three-variable crosstab helps strengthen our understanding of the “focal relationship” involving our dependent and independent variables; testing a relationship for possible spuriousness helps to meet the nonspuriousness criterion for causality; identifying an intervening variable can help chart the causal mechanism by which variation in the independent variable influences variation in the dependent variable; and specifying the conditions when a relationship occurs can help improve our understanding of the nature of that relationship.
