Establishing clear eligibility criteria for inclusion in a study sample is an important step in research design. Eligibility criteria define the characteristics that individuals must possess in order to be included in the sample. By establishing clear eligibility criteria, a nurse researcher can increase the homogeneity of the sample, meaning that the individuals in the sample will have similar characteristics. This can improve the internal validity of the study by reducing the potential for confounding variables.
Clear eligibility criteria can also help to decrease the size of the sample, which can be beneficial in terms of cost and feasibility. By excluding individuals who do not meet the eligibility criteria, the sample can be more focused and targeted, leading to more precise results.
In summary, clear eligibility criteria are important for establishing a focused and homogenous sample, which can improve the internal validity of the study.
