Sample Variance Bernoulli Distribution. I am facing the following problem, given x1.xn a random sample of bernoulli(θ) variables find the distribution of the sample variance s2=1n∑i . All three have the same expected value, .

The bernoulli distribution is a special case of the binomial distribution where a single trial is conducted (so n would be 1 for such a binomial distribution). When each of the independent random variables. The probability of success in this example was 0.6, probability of failure was 0.4.

When each of the independent random variables.

In general, whenever we have repeated, . That's our variance right over there. The variance of a bernoulli random variable is: Recall that the mean of the bernoulli distribution is µ = p and its variance is σ2 = pq.
