The

**standard deviation for the binomial distribution**is defined as:σ = √n*p*(1−p)

where

*n*is the sample size and*p*is the population proportion.To calculate the standard deviation for a given binomial distribution, simply fill in the values below and then click the “Calculate” button.

σ = **16.56**

**Explanation:**

σ = √n*p*(1−p)

σ = √40*0.43*(1−0.43)

σ = **16.56**
