Question

Quizplus · Accepted Answer

Reliability is the extent to which a measurement tool produces consistent results. A scale that gives different weight measurements every time it is used is not reliable, making D the best answer. Face validity refers to how well a measure appears to measure what it is supposed to measure, construct validity refers to whether a measure adequately assesses a specific concept or construct, split-half validity refers to the extent to which a test is consistent within itself, and random-half validity is not a recognized validity type.
