Quizplus · Accepted Answer

The best choice for a matching variable in the matched groups design is the same measure that will be used as the dependent variable. This helps to control for individual differences that may affect the results, allowing for a more accurate comparison between the experimental and control groups. Choosing a different variable (A) or one that is unreliable or invalid (C) may introduce confounding variables that could impact the results. An inexpensive and quick test (B) may not necessarily be relevant to the study and may not effectively match participants based on the dependent variable.
