Validation Theory

Validation Theory in measurement focuses on ensuring that the tools we use to assess various qualities—like tests, surveys, or metrics—accurately measure what they are intended to measure. It involves evaluating factors such as the reliability of the measurement (consistency over time) and the validity (how well the tool captures the intended concept). Essentially, it’s about confirming that our measurements truly reflect the reality we aim to understand, providing confidence that decisions based on those measurements are sound and meaningful.
