Question

Quizplus · Accepted Answer

This situation described represents a failure to control for the confounding variable of history, which refers to specific events or occurrences that take place between the pretest and posttest and affect the outcome being measured. Maturation refers to natural, developmental changes that occur over time and can also influence the posttest results, but it is not specific to events occurring between the pretest and posttest. Randomization, pretest sensitivity, and reactivity all refer to methods of controlling for extraneous variables or biases, but they are not directly related to the situation described.
