Overview of Quantitative Research

Quantitative research helps medical educators and researchers use data to understand and improve learning, teaching, and program outcomes. Applying statistical methods to summarize and compare results makes it possible to measure change, identify patterns, and evaluate educational efforts, such as new curricula, wellness initiatives, or assessment of programs. This article introduces key ideas for using quantitative methods effectively in medical and family medicine education, including how research questions connect to study design, common approaches such as experimental, quasi-experimental, and correlational studies, and practical ways to collect data through surveys, observations, or existing records. Examples from medical education illustrate how these methods can be used to evaluate programs, describe learner progress, and test innovations. The paper also outlines common challenges—such as drawing broad conclusions from small samples, confusing association with cause, or using measures that do not fully capture what is intended—and offers strategies to address these problems. The paper aims to help clinician-educators apply quantitative methods with greater confidence and clarity.
