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. Web2 de jul. de 2024 · Skewed to the Left . The situation reverses itself when we deal with data skewed to the left. Data that are skewed to the left have a long tail that extends to the left. An alternate way of talking about a data set skewed to the left is to say that it is negatively skewed. In this situation, the mean and the median are both less than the mode.
