Quizplus · Accepted Answer

Chebyshev's Theorem applies to any data set and provides a lower bound on the proportion of observations that occur within k standard deviations of the mean, where k is any positive number greater than 1.0. It states that at least 1 - (1/k^2) of the observations fall within k standard deviations of the mean.
