The term "sample size" refers to the number of observations or data points in a statistical sample. It is an important factor when conducting surveys, opinion polls, experiments and other forms of research that involve collecting information from a specific group of people. The sample size determines how accurately the results can be generalized to the larger population being studied. A larger sample size typically leads to more accurate results, but also requires more time, resources and effort to gather data. Therefore, it is essential for researchers to carefully consider the appropriate sample size based on their specific research objectives, available resources, and level of accuracy required in their findings.
