Where: z = 1.96 for a confidence level (α) of 95%, p = proportion (expressed as a decimal), n = sample size. The Margin of Error (MOE) Calculator uses the following formulas: 1. MOE = z * √p * (1 – p) / √n 2. MOE (with finite population correction) = z * √p * (1 – p) / √(N – 1) * n / (N – n) N is the population size.
