Main effect
From Wikipedia, the free encyclopedia
Main effect is the term used in research methods for the effect that is produced by the average of an dependent variable that has been produced over another dependent variable. For example, the dependent variable A is paired with dependent variable B to produce the main effect.
For example, in factorial designs, the main effect is what the independent variables elicit when averaged out over each other.
