It is possible to use one of them to construct a table that suggests the optimal ,sample size, – given a population ,size,, a ,specific, margin of ,error,, and a desired confidence interval. This can help researchers avoid the formulas altogether. The table below presents the results of one set of these calculations.

Where: p – Sample Proportion (fraction of sample which is a success); Now to find the desired z score, you need to know the confidence interval of the sample because the Z score is dependent on that.Below table is given to see the relation of a confidence interval and z score:

Calculating the Number of Respondents You Need

Sample ,size, requirements vary based on the ,percentage, of your sample that picks a particular answer. For example, if in a previous survey you found that 75% of your customers said yes they are satisfied with your product and you are looking to conduct that survey again, you can use p = 0.75 to calculate your needed sample ,size,.
