Mean and Standard Deviation of Binomial Distribution Binomial distribution comes from a series of Bernoulli trials (an experiment with two outcomes, "suceess" and "failure", where we translate "success" as the number 1, and "failure" as zero). The basic question: How many successes can we ...

Standard deviation, in statistics, a measure of the variability (dispersion or spread) of any set of numerical values about their arithmetic mean (average; denoted by μ). It is specifically defined as the positive square root of the variance (σ2); in s
