Population size refers to the total number of people within your demographic. The sample size is a significant feature of any empirical study in which the goal is to make inferences about a population from a sample. Set your confidence level.
To do this use the confidence interval equation above but set the term to the right of the sign equal to the margin of error and solve for the resulting equation for sample size n.
Since it not possible to survey the whole population we take a sample from the population and then conduct a survey or research. 603 respondents are needed and that becomes your sample size. To do this use the confidence interval equation above but set the term to the right of the sign equal to the margin of error and solve for the resulting equation for sample size n. For example if you use a confidence interval of 4 and 47 percent of your sample picks an answer you can be sure that if you had asked the question of the entire relevant.
