Data analysis and research require carefully planned and executed studies to achieve accurate results. One of the fundamental steps in these processes is determining an appropriate sample size. Sample size is a critical decision regarding which data will be collected and analyzed, and selecting the wrong sample size can adversely affect the outcomes.
In this article, we will delve into the topic of calculating sample size. We will specifically focus on one of the three primary methods—using formulas—out of which you can choose to determine your sample size.
We will also explore how to calculate sample size in research studies that examine the frequency of events and those that examine the average occurrence. Additionally, we will address which formulas to use when the population size is either unknown or known.
