Which of the following is important to include in defining a good research study?

In defining a good research study, including a description of the sample and how it was obtained is crucial. A well-defined sample provides clarity on the population being studied and ensures that the findings can be understood in context. It informs readers about the characteristics of the participants, such as their demographics or specific criteria for inclusion. This information is vital for assessing the generalizability of the study's results to a broader population.

Additionally, detailing how the sample was obtained helps to evaluate the rigor and potential biases in the study design. It enhances transparency and allows for the assessment of the methodology, which is essential for replicating the study and validating its findings. Without a clear understanding of the sample and recruitment methods, it becomes difficult to gauge the reliability and applicability of the results, making this aspect foundational in research reporting.
