## Resource

This ten-question practice quiz focuses on core research methodology concepts essential for the EPPP, covering topics such as experimental and quasi-experimental designs, internal and external validity, factorial designs, measurement scales, and threats to validity. Each item includes a clear stem, multiple-choice options, the correct answer, and a detailed rationale that explains why the selected response is accurate while distinguishing it from common misconceptions. The content is designed to strengthen candidates’ understanding of scientific inquiry in psychology, emphasizing practical application of methodological principles in clinical, developmental, and organizational contexts. It serves as an effective study tool for reinforcing key knowledge areas tested on the Examination for Professional Practice in Psychology.
