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.

05.05.2021 · Chebyshev’s theorem is used to find the minimum proportion of numerical data that occur within a certain number of standard deviations from the mean. In normally-distributed numerical data: 68% of the data are within 1 standard deviation from the mean. 95% of the data are within 2 standard deviations from the mean.
Chebyshev's inequality - Wikipedia
https://en.wikipedia.org/wiki/Chebyshev's_inequality
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 deviationsaway from the mean (or equivalently, over 1 − 1/k of the distribution's values are less than k standard deviations away from 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/K2.

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. And since 3 4 = 75 % that implies that 75% of the data values are between 123 and 179.

Chebyshev’s theorem is an amazing masterpiece of statistics which - unlike the empirical rule that applies to bell shaped distributions - holds regardless of the shape of the underlying distribution. 1 − 1 / k 2 (where k > 1) of the data lie within k standard deviations of the mean. So for instance to calculate the amount of data within 2 sd of the mean we put k = 2 which gives us 1 − 1 / 4 or 75% - we get the range of scores within 2 sd of the mean or 151 - 28 and 151 + 28.

Apr 19, 2021 · 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 – 120. Conversely, no more than 25% fall outside that range. An interesting range is ± 1.41 standard deviations.
