Quizplus · Accepted Answer

A main effect refers to the impact of a single independent variable while holding constant the influence of other independent variables in the study. It shows the effect of a single factor on the dependent variable, ignoring the impact of any other factors. Correlation coefficient is a statistical measure of the degree to which two variables are related to each other. A confound is a variable that systematically varies along with the independent variable, making it difficult or impossible to disentangle their effects on the dependent variable. An interaction effect occurs when the effect of one independent variable on the dependent variable depends on the level of another independent variable.
