Validity Types

Validity refers to how well a test or measurement accurately assesses what it’s supposed to measure. There are different types: - **Content validity** checks if the test covers all aspects of the concept. - **Construct validity** determines if the test truly measures the theoretical idea it claims to. - **Criterion-related validity** shows how well the test correlates with a related outcome or standard. In essence, validity ensures that the results are trustworthy and meaningful, reflecting the true nature of what’s being assessed.
