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
