What does the 'F' in research question appraisal signify?

The 'F' in research question appraisal stands for feasibility regarding participant recruitment. This aspect is crucial because it addresses whether the researcher can realistically gather the necessary participants for their study within the constraints of time, budget, and available resources. Evaluating the feasibility helps ensure that the research question is not only relevant but also practical to investigate. By ensuring there are enough participants who meet the study's criteria, researchers can obtain sufficient data to draw meaningful conclusions, thus enhancing the validity of the research findings.

While the other choices relate to important aspects of research, they do not specifically represent the 'F' in the context of question appraisal. Understanding feasibility is a foundational step that allows researchers to plan effectively and identify potential obstacles early in the research process.
