The Empirical Rule is an approximation that applies only to data sets with a bell-shaped relative frequency histogram. It estimates the proportion of the measurements that lie within one, two, and three standard deviations of the mean. Chebyshev’s Theorem is a fact that applies to all possible data sets. WebDec 11, 2024 · Chebyshev’s inequality is broader; it can be applied to any distribution so long as the distribution includes a defined variance and mean. Chebyshev’s inequality states that within two standard deviations away from the mean contains 75% of the values, and within three standard deviations away from the mean contains 88.9% of the values. roberts rules on ad hoc committees
