Book Description: This book examines test validity in the behavioral, social, and educational sciences by exploring three fundamental problems: measurement, causation and meaning. However, formally assessing the validity of a specific use of a test can be a laborious and time-consuming process. Internal validity dictates how an experimental design is structured and encompasses all of the steps of the scientific research method.

Predictive validity, in contrast, is where one variable occurs earlier and is supposed to anticipate any later behavior. Reliability is the consistency of the responses to measure under three conditions: (1) when retested on the same person; (2) when retested on the same measure; and, (3) similarity of responses across items that measure the same characteristic.
