Sample Size Calculator
In statistics, sample size is very useful to measure the amount of observations in the sample population. It aids to calculate the difference in-between the population from sample.
The formula to calculate sample size is given below:
where,
SS = Sample Size
Z = Z value (example, 1.96 for 95% confidence level)
p = Percentage of population (expressed in decimal. For example, 0.5 used for sample size needed)
C = Confidence level (expressed in decimal. Example, 0.04 = + 4)
Pop = Population
Enter the inputs in the below online sample size calculator and then press calculate to find the sample size for finite and infinite population.
