How to Find the Variance of Binomial Distribution?
The steps to find the variance of binomial distribution are given below:
- First, identify the number of trials and probability of success
- Then, identify the probability of failure is given or not. If the probability of failure is not present, then determine it by 1 – probability of success.
- Then use the variance of binomial distribution formula i.e., σ2 = npq
- The resultant value gives the variance of the binomial distribution.

Variance of Binomial Distribution
Variance of Binomial Distribution is a measure of the dispersion of probabilities with respect to the mean value (expected value). This value tells us the typical extent to which sampled observations tend to differ from the expected value.
In this article, we will explore the variance of the binomial distribution, the formula for variance in the binomial distribution, and the derivation of the variance formula for the binomial distribution. We will also solve some examples related to the variance of the binomial distribution. Let’s begin our learning journey on the topic of the Variance of Binomial Distribution.”
