Definitions:

Correlated

When two or more variables or sets of data are related in some way, indicating a relationship or dependence between them.

Multicollinearity

A situation in multiple regression models where one predictor variable in the model can be linearly predicted from the others with a substantial degree of accuracy, leading to difficulties in determining the separate effects of predictor variables.

Dependent Variable

The outcome variable in an experiment or study that researchers wish to explain or predict, which changes in response to the independent variable.

Explanatory Variables

Variables in a statistical model that are used to explain variations in the dependent variable; also known as independent variables.
