Dr. Darden's concern about whether or not the final exam accurately measures a student's accumulated knowledge about core concepts from the physics course indicates that he is most concerned with the validity of his final exam. Validity refers to whether or not a test measures what it is intended to measure. While reliability (A) is important, it refers to the consistency of scores obtained by a test, whereas standardization (B) refers to the process of administering and scoring a test in a consistent and uniform manner. Confounding factors (C) are variables that can influence the results of a study but are not accounted for by the researcher. Although confounding factors can impact a test's validity or reliability, Dr. Darden's primary concern is with the validity of his final exam.
