Alternate Forms Reliability

Alternate Forms Reliability is a way to measure the consistency of a test by comparing different versions of the same test. For example, if you give two different quizzes that assess general knowledge but cover similar topics, a high correlation in scores indicates that both quizzes are reliable measures of a person’s knowledge. This method helps ensure that the results are not dependent on the specific questions but reflect the person's actual understanding of the material. Essentially, it checks if the test delivers consistent results, regardless of the specific version administered.
