Definitions:

Independent Variables

Variables in an experiment or study that are manipulated or controlled by the researcher to investigate their effects on dependent variables.

Dependent Variable

The factor in a study or experiment that is anticipated to vary as a result of alterations in the independent variable.

Explained Variation

The portion of the total variation in a dataset that is accounted for by the model's predictions.

Random Error Term

Represents unexplained variability within a statistical model, capturing the random variance that is not accounted for by the explanatory variables.
