Understand the concept of reliability in psychological testing: Reliability refers to the consistency of a test in measuring what it is intended to measure. A reliable test will yield similar results under consistent conditions.
Identify the method used by Dr. Armen: He administers the same test to the same group of students after a two-week interval.
Recognize the purpose of this method: By giving the test twice, Dr. Armen is checking if the test results are consistent over time, which is a key aspect of reliability.
Differentiate reliability from other concepts: Validity refers to whether the test measures what it claims to measure, standardization involves ensuring the test is administered consistently, and norms refer to the average scores established for a test.
Conclude that Dr. Armen is assessing the reliability of the test, as he is interested in the consistency of the test results over time.
