A sample is the group of people who take part in the investigation. Moreover, studies with pragmatism research philosophy can integrate the use of multiple research methods such as qualitative, quantitative and action research methods. Other advantages of this methodology include eliminating the phenomenon of clustered selection and a low probability of contaminating data. Pragmatic randomized controlled trials should be designed with a conscious effort to generate evidence with a greater external validity by making the research question as similar as possible to the questions faced by clinical decision-makers (i.e., patients and their families, physicians, policy makers and administrators) and then answer that question with rigor.
