The standard deviation of the binomial distribution is ____?
- √npq
- √np
- npq
- None of these
Explanation
The standard deviation of a binomial distribution is indeed √npq, where:
- n is the number of trials
- p is the probability of success
- q is the probability of failure (q = 1 - p)
The formula for the standard deviation of a binomial distribution is:
σ = √npq
This represents the spread or dispersion of the distribution.
