WebHow to calculate margin of error n = sample size • σ = population standard deviation • z = z-score Get the population standard deviation (σ) and sample size (n). Take the square root … WebTo carry out this calculation, set the margin of error, ε, or the maximum distance desired for the sample estimate to deviate from the true value. 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.
