An extraneous variable is a variable that has an unpredictable impact on the dependent variable. It is different from the independent variable, which is the variable that is intentionally manipulated in the study. A moderator variable is a variable that influences the strength or direction of the relationship between the independent and dependent variables, but it is not unpredictable like an extraneous variable. "Wild variable" is not a commonly used term in research methodology.
