A) Using more precise measurements
B) Using more reliable measurements
C) Using a pretest/posttest design
D) Collecting measurements from more people
E) All of the above can be done to reduce measurement error

Question

Quizplus · Accepted Answer

Using a pretest/posttest design can help control for measurement error by allowing for comparison between pre- and post-intervention measurements. However, it does not directly reduce measurement error itself. Choices A, B, and D can all directly reduce measurement error by improving precision, reliability, and sample size respectively. Therefore, option E is incorrect.
