WebIn probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive, zero, negative, or undefined. For a unimodal distribution, negative skew commonly indicates that the tail is on the left side of the distribution, and positive … WebAboutTranscript. When we describe shapes of distributions, we commonly use words like symmetric, left-skewed, right-skewed, bimodal, and uniform. Not every distribution fits one of these descriptions, but they are still a useful way to summarize the overall shape of many distributions. Sort by:

The scores of 65 to 75 are half of the area of the graph from 65 to 85. Because of symmetry, that means that the percentage for 65 to 85 is ½ of the 95%, which is 47.5%. WebNotes.

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.
