Quizplus · Accepted Answer

Validity refers to whether a test measures what it is intended to measure. In this case, determining if Dr. Kaesser's test measures persuasiveness would be an assessment of its validity. Reliability (A) refers to the consistency of results over time or across evaluators, consistency (C) is similar to reliability, and objectivity (B) refers to the degree to which a test or measurement is free from subjectivity or bias. While these factors are important in evaluating a test or measure, determining whether the test measures the intended construct (persuasiveness) is the most important assessment of the test's usefulness.
