Validity measurement

Validity measurement refers to how accurately a test or measurement reflects what it intends to assess. For example, a valid student test genuinely measures the student's understanding of the material, not other unrelated skills. Ensuring validity means checking that the results truly represent the concept being studied, rather than being influenced by errors or irrelevant factors. It's a key quality indicator in research and assessments, confirming that the conclusions drawn are based on accurate and relevant data. In essence, validity ensures that you're measuring what you think you're measuring.
