Many interactions are found with categorical variables but few with continuous variables, suggesting that, from a mathematical point of view, investigating interactions with continuous variables is less powerful than with categorical variables. This issue is analyzed from three other points of view: study design, measurement of the independent…

This paper presents a discussion of various statistical concepts and techniques in light of two propositions. The first is that researchers need to select analytical techniques that prevent them from committing Type VI errors, which are inconsistencies between the research question and the statistical analysis. The second is that many statistical…

Given that theory is a crucial component of path analysis and that major theories in the social sciences either directly or by inference assume interaction, it appears that interaction has to be considered in path analytic models that reflect those theories. The use of interaction within the framework of path analytic methodology is investigated…
