Question

Quizplus · Accepted Answer

A measure can be reliable but not necessarily valid. Reliability refers to the consistency and stability of the measure over time and across different observers, while validity refers to the degree to which a measure accurately reflects the concept it is intended to measure. A measure can be consistent and stable, but still not accurately measure the concept of interest, meaning it is reliable but not valid.
