Question 1008287: In the formula for variance of values in a sample ∑(x-xbar)^2/n-1, what is required for the variance to equal zero?
The Empirical Rule indicates that we can expect to find what proportion of the sample included within + or - 2 sd? Answer by stanbon(75887) (Show Source):

----
Every value of x is the same, so x = xbar
