Binomial distribution skewness
WebA binomial experiment takes place when the number of successes is counted in one or more Bernoulli Trials. Example 4.9 At ABC College, the withdrawal rate from an … WebFor example, if p = 0.2 and n is small, we'd expect the binomial distribution to be skewed to the right. For large n, however, the distribution is nearly symmetric. For example, here's a picture of the …
