If not, it"s not as good of a measure, because the results we get are partly a function of when we do the test. Investigator applies the measure once and then applies it again to the same units of analysis. If the measure if reliable, then two results should be same or similar. Different way of getting at the same outcome (sat scores and gpa) Methodological extension of split half method: compress consistency . Even if it is reliable, a measurement can be wrong.
