The Sample Size Calculator - Slovin's Formula

The Slovin’s formula is used to estimate the sample size needed to create a realistic model using the population size and the acceptable margin of error:

n = N / (1 + Ne^2)

The following calculator allows you to apply the Slovin’s formula and find the sample size.

You need to provide the population size N and the acceptable margin of error e:

Usually 1 to 5%

Sample size (n): 171

I hope this calculator is useful. Happy analyzing!
