Correct Answer - Option 1 : 0

Explanation:

As there is no spread of variables around the mean, the variance for the degenerate distribution is zero (Var(X) = 0).

The symbol of Sample variance = S

S = ∑(x - x̅ )2/(n - 1)

x̅ = mean of all observation

x = value of the observation

n = number of observations

variance is the expectation of the squared deviation of a random variable from its mean
