ABSTRACT

While determining suitable sample size and sampling is one of the most crucial factors to take into account during the planning stage of a research project, researchers sometimes encounter difficulties in this regard. Inadequate sample sizes are commonly used by researchers, which always results in inaccuracies in the conclusions. The purpose of this methodological review is to highlight the importance of sample size estimation and sampling techniques and offer suggestions for describing sample sizes in an easy-to-understand way. A brief overview of sample size calculation in health sciences research and the terminology used are provided. Techniques for estimating the sample size for health research are described with examples depending on the kind of study design. To estimate sample size, researchers must: Be aware of the statistical analysis that will be used; Decide on acceptable precision levels; Decide on study power; and specify the confidence that will be used. This method review's displays a thorough explanation and simplicity of the sampling technique and the sample size formula that will assist in clarifying the mystery surrounding statistical equations for sampling technique and sample size estimates in healthcare and social science research.
