How do you determine the sample size?

The sample size is the number of individuals who are included in a survey or experiment. Determining the sample size for a study is an important factor in research design as it affects the power and accuracy of a study's results. Sample size can be determined by taking into account the precision required for a study, the population size, and the confidence level desired in the study's conclusion. It is important to ensure the sample size is representative of the population being studied, as this improves the accuracy of the study's results. Additionally, researchers must consider the resources they have available and the amount of time and money they are willing to spend on a study when determining the sample size.

The sample size in the number of population elements chosen in the sample. Considerations include the importance of the decision, the nature of the research, the sampling methods, and resource constrains. The sample size should be big enough to be sufficient to make results sound, and to be convincing.
