Module 3: Discussion How do researchers determine reliability in a study? Describe the major types of each. “Reliability testing is a measure of random error in the measurement technique” (Grove, Grey, & Burns, 2015, p.288). Researchers use various methods to determine reliability in a study. Frist, there is test-restest reliability. This method is generally used with physical measures, technological measures, and paper and pencil scales (Grove, Grey, & Burns, 2015, p.289). The Second method is interrater reliability, which is referred to as the comparison of two observers or two judges in a study (Grove, Grey, & Burns, 2015, p.290). Then there is the alternate forms reliability, which is the comparison of two paper and pencil instruments (Grove, Grey, & Burns, 2015, p.290). Lastly, there is homogeneity. It is a “type of reliability testing used primarily with paper and pencil instruments or scales to address the correlation of each question to the other questions within the scale” (Grove, Grey, & Burns, 2015, p.290).
