What does validity mean in research design?

• A. Validity measures the consistency of results over repeated trials
• B. Validity assesses the reliability of an assessment
• C. Validity indicates how well an assessment measures what it is intended to measure
• D. Validity refers to the breadth of topic coverage in an assessment

Answer: (C)

Validity in research design is fundamentally concerned with the accuracy and effectiveness with which an assessment or study measures the intended concept or variable. When we say that an assessment is valid, we are asserting that it truly reflects the characteristic or construct it aims to measure. This is critical in ensuring that the outcomes of a study are meaningful and can be relied upon to draw conclusions about the hypotheses being tested or the research questions posed. In this context, validity encompasses several types, such as construct validity, content validity, and criterion validity, all of which help researchers determine if the measurement tools they are using are appropriate for their specific research objectives. A high degree of validity means that the findings can confidently be applied to the wider context or to make specific predictions. While reliability (the consistency of results) and coverage (the extent of topics included) are important in research design, they do not define validity itself. The focus of validity is exclusively on the extent to which the measurement aligns with the intended purpose.
