How does the reliability of a study affect its validity?
If our depression researchers were sloppy in ensuring the validity or reliability of their questionnaire, it could affect the believability of their study’s overall results. Although you can never prove reliability or validity conclusively, results will be more accurate if the measures in a study are as reliable and valid as possible.
Why is content validity so important in statistics?
