Describe the major types of each.  As a member of a journal club that is discussing the instructor assigned article in this course, what would you identify as strengths and / or weaknesses of the reliability and validity section of this article? Hint: Use Chapter 10 to help you answer these questions. Reliability in research is define as the consistent measurment of data. Researchers determine reliability in a study by different measures to achieve results. The four types of major reliabilty are test-retest, homogeneity, alternate forms, inter-rater. Test-retest is when you run the same test on a subject or indivual on different occassions using the same measurements. An example of a test-retest is monitoring of a patient vital signs on a monitor. Homogeneity measure the relationship between two things or items to determine the results. An example of a
