Suppose you know a dataset has a mean of 100 and a standard deviation of 10, and you’re interested in a range of ± 2 standard deviations. Two standard deviations equal 2 X 10 = 20. Consequently, Chebyshev’s Theorem tells you that at least 75% of the values fall between 100 ± 20, equating to a range of 80 … See more Chebyshev’s Theorem helps you determine where most of your data fall within a distribution of values.

In probability theory, Chebyshev's inequality (also called the Bienaymé–Chebyshev inequality) guarantees that, for a wide class of probability distributions, no more than a certain fraction of values can be more than a certain distance from the mean. Specifically, no more than 1/k of the distribution's values can be k or more standard deviations away from the mean (or equivalently, at least 1 − 1/k of the distribution's values are less than k standard deviations away from the mean… improve your aim gameWebBy Chebyshev’s Theorem, at least 3/4 of the data are within this interval.
