Validity and Reliability by Mind Map: Validity and Reliability

1. The adequacy of validity evidence depends on both the strength of the validity coefficient and the purpose the test is being used

2. Validity: Does the test measure what it is supposed to measure?

3. Reliability: Does the test yield the same or similar score rankings (all other factors being equal) consistently?

4. Accuracy: Does the test score fairly closely approximate an individual’s true level of ability, skill, or aptitude?
