Each time you specify a set of parameters n and p, a particular binomial probability distribution can be generated.
Shape. Binomial distributions can be symmetrical or skewed. Whenever p = 0.5, the binomial distribution will be symmetrical, regardless of how large or small the value of n. However, when p ≠ 0.5, the distribution will be skewed. If p < 0.5, the distribution will be positive or right skewed. If p > 0.5, the distribution will be negative or left skewed. The closer p is to 0.5 and the larger the number of observations in the sample, n, the more symmetrical the distribution will be.
Mean. The mean of a binomial distribution is the product of the sample size, n, and the probability of success, ...
