How do you improve measurement reliability? Discuss the three methods of improving measurement reliability.
What will be an ideal response?
Ans: We improve measurement reliability by adhering to the rules of research and by following the guidelines for the three main ways of doing so; inter-observer or inter-rater reliability, test-retest reliability, and internal consistency reliability. Students should discuss each and then show how they help in maintaining measurement reliability. They should discuss the need for having more than one researcher during data collection if possible, and having another researcher check the data separately for consistency, and the importance of adding more than one question to measure a construct.
