In this assignment, you will discuss ways to gather evidence of a test’s reliability and validity. In a 4 – 6 page paper, describe different types of reliability estimates and forms of validity. Then, explain how a test developer or test user could gather evidence of a test’s reliability and validity.
Be sure to address the following in your paper:
Define the concept of reliability.
Explain the meaning of a reliability coefficient.
Explain how a test developer or test user could gather evidence for the test’s reliability using two reliability estimates (i.e., test-retest, parallel-forms, alternative forms, split-half, and internal consistency reliability estimates). For example, how might a test developer who has developed a new psychological test measure test-retest reliability?
Define the concept of validity.
Explain the meaning of validation.
Explain how a test developer or test user could gather evidence for a test’s face validity, content validity, construct validity, and criterion-related validity. For example, how might a test developer who has just developed a new psychological test gather evidence that the test has content validity?
Cite three or more scholarly sources.
