An experiment has a high degree of internal validity when it shows convincingly that changes in behavior are a function of the independent variable and not the result of unknown variables.
<h3>What is internal validity and example?</h3>
Internal validity makes the conclusions of a causal relationship credible and trustworthy. Without high internal validity, an experiment cannot demonstrate a causal link between two variables. Research example You want to test the hypothesis that drinking a cup of coffee improves memory.
Controls are required to assure internal validity (causality) of research designs, and can be accomplished in four ways:
- (1) manipulation,
- (2) elimination,
- (3) inclusion,
- (4) statistical control,
- (5) randomization.
