Question

Quizplus · Accepted Answer

Test-retest, interrater, and internal consistency are all measures of the reliability of a research tool or instrument, meaning they are concerned with how consistent or stable the results are over time, across different raters, or among different items within a scale. Validity, on the other hand, refers to how accurately the tool or instrument measures what it is intended to measure, while correlation refers to the degree of association between two variables. Legitimacy is not a relevant concept in this context.
