Instead they must find already existing examples of the independent variable and investigate how changes in this variable affect the dependent variable.
They are variables concepts that can vary. This variable is chosen manipulated and measured by the researcher aimed at figuring out its relationship with other variables. Instead they must find already existing examples of the independent variable and investigate how changes in this variable affect the dependent variable. Categorical variables represent groupings of some kind.
