      1. Mean and Standard Deviation of Binomial Process . Clarification. These formulas cannot be used to get the mean and standard deviation of any binary variable (e.g., coded 1/2 or –1/1). Rather they give the mean and variance of the total number of 'positive' outcomes of binary variables. Expected Value (Mean) of a Binomial Distribution

      Since the Poisson distribution arises from the Binomial distribution as a limiting case as n (, p 0, in such a way that np = ( (a constant), it gives a good approximation to the Binomial distribution for large n and small p. So, if a random variable X has a binomial distribution given by X ~ Bin(n,p) and n …

      Mean and Standard Deviation of Binomial Probability Distributions. Two features that help describe the graph of any distribution are the balance point of the distribution and the spread of the distribution about the balance point. Balance Point – mean (μ) of the distribution. The mean is the expected value of the number of successes.
