Abstract
McClelland and Judd (199 3) concluded that many interactions have been found with categorical variables, but few with continuous variables. Using a mathematical point of view, they concluded that investigating interactions with continuous variables was less powerful than with categorical variables. This article analyses the issue from three other points of view: design of the study, measurement of the independent variable, and nature of the question asked Our present conclusion is that the choice of either categorical or continuous interaction depends upon the research hypothesis being posed and the desired conclusions.
