WebIn 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 2 of the distribution's values can be k or more standard deviations away … WebFor k = 1, this theorem states that the fraction of all observations having a z score between -1 and 1 is (1 - (1 / 1)) 2 = 0; of course, this is not a very helpful statement. But for k ³ 1, Chebyshev's Theorem provides a lower bound to the proportion of measurements that are within a certain number of standard deviations from the mean. This ... WebStep 1: Calculate the mean and standard deviation. The example provides the required information. Step 2: Determine the minimum proportion of observations using Chebyshev's theorem.
