Main Effects
The direct influence of an independent variable on a dependent variable in an experimental study.
Independent Variable
A variable in an experiment that is manipulated or changed to observe its effect on a dependent variable.
Dependent Variable
In statistical analysis, this is the variable that is being tested and measured, often seen as the outcome influenced by independent variables.
