Step 1: Firstly, determine the population size, which is the total number of distinct entities in your population, and it is denoted by N.How to Calculate Sample Size? (Step by Step) How to Calculate Sample Size? (Step by Step).Formula to Determine Sample Size of Population.Standard deviation divided by the sample size, multiplying the resultant figure with the critical factor. Its equation can derive using population size, the critical value of the normal distribution, sample proportion, and margin of error Margin Of Error The margin of error is a statistical expression to determine the percentage point the result arrived at will differ from the actual value. As such, determining the appropriate sample size is one of the recurrent problems in statistical analysis. In other words, it is the minimum size needed to estimate the true population proportion with the required margin of error and confidence level. So, the sample size must be adequate to make meaningful inferences. The term “sample” refers to the portion of the population that enables us to draw inferences about the population. The sample size formula helps calculate or determine the minimum sample size, which is required to know the adequate or correct proportion of the population, along with the confidence level and the margin of error.
