Which one of the following selection tests answers the question “Does this test measure what it’s supposed to measure”?

Correct option is D

The term Test Validity refers to whether a test measures what it is intended to measure. It encompasses various types of validity, such as content, criterion, and construct validity, which assess different aspects of the test's accuracy and appropriateness.
Explanation of the Options:
· (a) Content Validity:
· Determines whether the test covers the entire range of the concept being measured (e.g., a mathematics test covering all relevant topics).
· (b) Criterion Validity:
· Assesses how well the test correlates with an outcome or criterion (e.g., a test predicting job performance).
· (c) Construct Validity:
· Examines whether the test truly measures the theoretical construct it is designed to measure (e.g., intelligence, motivation).
· (d) Test Validity:
· An umbrella term that ensures the overall accuracy and relevance of a test in measuring what it claims to measure.
Information Booster:
Types of Test Validity:
1. Content Validity: Focuses on the test's scope and comprehensiveness.
2. Criterion Validity: Evaluates test performance against a benchmark.
3. Construct Validity: Ensures alignment with theoretical concepts.
Importance of Test Validity:
· Validity is crucial for ensuring that decisions based on test results (e.g., hiring, admissions) are fair, reliable, and aligned with the intended purpose.
Additional Knowledge:
· Reliability vs. Validity:
· A test can be reliable (consistent results) but not valid (not measuring the intended construct).
· Validity ensures both accuracy and meaningfulness.
