Verified step by step guidance

1. Understand the concept of 'validity' in psychological testing: Validity refers to the degree to which a test accurately measures what it is intended to measure. It is a crucial aspect of test design and evaluation.
2. Differentiate between 'validity' and 'reliability': While validity is about the accuracy of the test, reliability refers to the consistency of the test results over time. A test can be reliable without being valid, but it cannot be valid without being reliable.
3. Consider the role of 'objectivity' in testing: Objectivity refers to the extent to which test results are not influenced by the examiner's biases or subjective judgments. It is important for ensuring fairness in testing.
4. Examine the concept of 'consistency' in the context of psychological tests: Consistency is closely related to reliability and refers to the stability of test scores across different administrations or forms of the test.
5. Conclude by identifying that the correct term for a test measuring what it is supposed to measure is 'validity', as it directly addresses the accuracy and appropriateness of the test in assessing the intended construct.
