WebThe conditions n*p > 10 and n*q > 10 ensure that p is not too close to 0 or 1. For any given value of n, if p is too close to 0 or 1, then the distribution of the number of successes in a binomial distribution with n trials and success probability p would be significantly asymmetric about its mean (and so significantly non-normal). 4 comments. sharon ramey facebookWebMay 10, 2024 · There are several formulas to measure skewness.
