What best describes the difference between quantitative and qualitative research in PT education?

• A. Quantitative data is collected through numerical measurement.
• B. Qualitative research ignores participant perspectives.
• C. Qualitative research uses statistical analysis as its primary method.
• D. Quantitative measures numerical data; qualitative captures experiences and perceptions; both can inform practice.

Answer: (D)

The main idea here is that quantitative and qualitative research approach PT education from different angles. Quantitative work measures things with numbers—exam scores, skill-check outcomes, time to complete a task—so you can analyze patterns, run statistics, and draw generalizable conclusions. Qualitative work, on the other hand, seeks deeper understanding of experiences, perceptions, and context—exploring what students and clinicians think, feel, and experience through interviews, focus groups, or open-ended observations, and then identifying themes from the data.

In PT education, you might use quantitative methods to quantify outcomes like graduation rates, board exam pass rates, or the average improvement in a functional assessment. You’d use qualitative methods to understand how students experience clinical rotations, what barriers they encounter in learning, or how they perceive the effectiveness of a particular teaching approach. Using both approaches together—often in mixed-methods research—gives a fuller picture: you know what changes occur and also why they occur, which helps shape curriculum design, teaching strategies, and assessment methods.

So the statement that best captures the difference is that quantitative measures numerical data, qualitative captures experiences and perceptions, and both can inform practice.
