Internal validity lends reliability and credibility to the findings of a causal relationship. Internal validity makes the conclusions of a causal relationship credible and trustworthy. You can achieve internal validity by controlling extrinsic variables and implementing random sampling. sometimes called selection bias - selecting research participants who differ from one another in ways that are related to the variables to be studied. A common measurement of this type of validity is the correlation coefficient between two measures. As a result, identifying potential confounding variables at the outset of the experiment is crucial.
