Types of reliability and how to measure them. Steps are taken to make sure the work’s findings are the result of experiences and ideas of the informants, and that evaluation findings are arrived at by considering solid evidence. The processes within the study are reported in detail, so that a future researcher can repeat the work As an informal example, imagine that you have been dieting for a month. If their research does not demonstrate that a measure works, they stop using it. Instead, they collect data to demonstrate that they work. Is it important to consider the findings of the study within the broader context of other people and settings, and whether similar projects and methods conducted in different environments would be of value. Psychologists do not simply assume that their measures work. Reliability in qualitative research: Credible Increase the number of questions on a multiple choice exam that address the same learning outcome. Recalculate interrater reliability until consistency is achieved. Conducting norming sessions to help raters use rubrics more consistently.

The same test conducted by different people.ĭifferent versions of a test which are designed to be equivalent. Interrater reliability number of agreements/number of possible agreements. Reliability in quantitative research: Test-retest

the measurement could apply to others/the same result would happen each time.

the extent to which a research instrument consistently has the same results if it is used in the same situation on repeated occasions.
