• Does the measurement actually measure the larger concept or idea it is supposed to measure?

• Researchers look at other research and established measurements.

• Can use factor analysis to determine which variables go together.

• Sometimes called concept validity.

what is concurrent validity?

• Compares an assessment with another existing assessment that measures the same concept.

• The two assessments should produce similar results.

what is predictive validity?

what is pragmatic validity?

• Accuracy of a measuring instrument in predicting someone's current or future status.

• Focuses on whether the measurement is useful in real-world situations.

what is convergent-discriminant validity?

• Convergent: Different measurements of the same concept should produce similar results.

• Discriminant: The same measurements of different concepts should produce different results.

what is the relationship between reliability and validity?

• an assessment that is highly reliable does not have to be valid

• but, an assessment that is valid has to also be reliable
