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.
Ratio Level
A measurement scale that has a true zero point and equal intervals, allowing for the calculation of ratios.
