Question

In binomial distribution, the formula of calculating standard deviation is"

Answer 1

Answer

SD of binomial distribution

sigma(¶)=√npq

where,

n= number of trials

p=probability of success

q=probability of failure equal to 1-p

SO this is your answer

I hope you will find help from this

Answer 2

Standard Deviation of binomial distribution  is sigma(¶)=√nPQ

Explanation:

What is standard deviation?

A standard deviation is a measure of how distributed the data is with respect to the mean. A low standard deviation suggests that data are grouped around the mean, whereas a large standard deviation shows that data are more dispersed.

∴ Standard Deviation =√nPQ where,

n: The number of trials in the binomial experiment.

P: The probability of success on an individual trial.

Q: The probability of failure on an individual trial. (This is equal to 1 - P.)
