In controlled comparison research, the observed relationship between an independent variable (X) and a dependent variable (Y) may be caused by some other, uncontrolled compositional difference (Z). So, we always ask, “How else, besides the independent variable, are the groups I am comparing not the same?” For the hypothesis below, do the following: (i) Think up a plausible alternative causal variable. (ii) Describe how this variable might affect the relationship between the independent variable and the dependent variable. In a...
