Then the result is divided by the square root of the number of observations in the sample. Mathematically, it is represented as, Margin of Error = Z * ơ / √n
WebThe relevant variance is p (1-p), your calculation of √p (1-p) is the standard deviation. If that's not the reason, then note that Sal is working by treating "successes" as a 1 and "failures" a a 0, and then applying the typical variance formula - including division by n-1. The p (1-p) formula assumes division by n. WebAug 18, 2024 · For a covariate, the estimated marginal mean is the mean of Y for each group of the IV at one specific value of the covariate.
