Which of the following is the formula for the sample Variance when used as an estimate of of for a random sample of n observations from a population?
-
The formula for the sample variance is:
s^2 = Σ(x - x̄)^2 / (n - 1)
Where:
s^2 is the sample variance
Σ represents the sum of the values
x is each individual observation
x̄ is the mean of the sample
n is the number of observations in the sample
