Sample size calculation is more complex and crucial area of attention in a research process. Appropriate sample size of the study act as a strong foundation for evidence based practice, as small sample size may fail to detect the effect or large sample size may waste the resources. As a researcher we have to ensure that needed sample size is estimated to generate desirable power from the study, so that the findings could be generalized to the population. But it is difficult unless the researcher is aware about the influence of each component of the sample size estimates on sample size. This article briefly reviewed the relationship between the components of the sample size estimates and sample size.

Abstract


Sample size calculation is more complex and crucial area of attention in a research process. Appropriate sample size of the study act as a strong foundation for evidence based practice, as small sample size may fail to detect the effect or large sample size may waste the resources. As a researcher we have to ensure that needed sample size is estimated to generate desirable power from the study, so that the findings could be generalized to the population. But it is difficult unless the researcher is aware about the influence of each component of the sample size estimates on sample size. This article briefly reviewed the relationship between the components of the sample size estimates and sample size.
