Chebychev's inequality states that the "fraction of elements in the list that are k or more SDs away from the mean of the list is less than or equal to 1/k^2." It also says that the probability that "X is k or more SEs (standard error) away from E(X) (expected value) is less than or equal to 1/k^2."
