Consequently, what is Chebyshev's theorem formula? Chebyshev's theorem states for any k > 1, at least 1-1/k 2 of the data lies within k standard deviations of the mean. As stated, the value of k must be greater than 1. Using this formula and plugging in the value 2, we get a resultant value of 1-1/2 2, which is equal to 75%.

Now, since k > 1 we can use Chebyshev's formula to find the fraction of the data that are within k=2 standard deviations of the mean. Substituting k=2 we have −. 1 − 1 k 2 = 1 − 1 2 2 = 1 − 1 4 = 3 4. So 3 4 of the data lie between 123 and 179.

Chebyshev's Theorem
mathcenter.oxford.emory.edu › site › math117
This relationship is described by Chebyshev's Theorem: For every population of n values and real value k > 1, the proportion of values within k standard deviations of the mean is at least. 1 − 1 k 2. As an example, for any data set, at least 75% of the data will like in the interval ( x ¯ − 2 s, x ¯ + 2 s). To see why this is true, suppose a population of n values consists of n 1 values of x 1, n 2 values of x 2, etc. (i.e., n i values of each different x i in the population).

Use Chebyshev's theorem to find what percent of the values will fall between 123 and 179 for a data set with mean of 151 and standard deviation of 14. Solution −. We subtract 151-123 and get 28, which tells us that 123 is 28 units below the mean. We subtract 179-151 and also get 28, which tells us that 151 is 28 units above the mean.
Chebyshev’s Inequality - Overview, Statement, Example
https://corporatefinanceinstitute.com/.../chebyshevs-inequality
Chebyshev’s inequality is a probability theory that guarantees only a definite fraction of values will be found within a specific distance from the mean of a distribution. The fraction for which no more than a certain number of values can exceed is represented by 1/K 2 .
