Definitions:

Cause-effect Inferences

Logical deductions that suggest a relationship where one event (the cause) leads to the occurrence of another event (the effect).

External Validity

The extent to which research findings can be generalized to settings or groups outside the study.

Confounding Variables

External factors that can influence both the dependent and independent variables, potentially biasing the results of a study.

Independent And Dependent Variables

In experimental research, the independent variable is the factor that is manipulated to see its effect on the dependent variable, which is the outcome being measured.
