Test your ABA Terminology ➠ Indicators of Trustworthy Measurement

Trustworthy measurement: There are three indicators– validity accuracy, and reliability. Question: Which indicator of trustworthy measurement is defined by repeated measurement, yielding the same results? Answer: reliability. You measure something over and over again and you get the same result. You’ve got reliability. Versus accuracy, which looks at your observed values as compared to what actually happened, the true values. Think of accuracy as getting it right, it was correct; it’s what actually happened. Then validity doesn’t exactly entail measuring at all. Validity represents that what you measured, is what you set out to measure. Either it’s the right dimension of behavior, or the right behavior, or the behavior at the time that it’s most typically occurring, that’s validity.
