Methods in Behavioral Research, Ch. 5

When reading Chapter 5, we get the sense that measurement of a test's reliability is necessary; however, it is not enough to measure validity of the same test. Select your example from research on the topic of interest to you within psychology then follow the instructions below. Note: Ensure your example from research includes one of the types of reliability and one of the types of validity as those listed below.

• Test-retest reliability
• Internal consistency reliability
• Interrater reliability

• Face validity
• Content validity
• Predictive validity
• Concurrent validity
• Convergent validity
• Discriminant validity

Instructions: (a) Please summarize both concepts (reliability and validity) found in our text by Cozby and Bates (2015) or another credible source. (b) Then, summarize an illustration of those concepts found in your example from research related to your topic of interest within psychology. There might be variance in replies among you due to the example from research selected (e.g., experimental vs field research design). Our class discussion will likely relate to learning objectives/competencies 2.4 and 2.5 as dependent on peer selections, research examples, and replies.  The participation rubric is in the Instructor Policy document.  Word count range: 1000 excluding citations of your sources.
