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.

In cell B2, enter the Chebyshev Formula as an excel formula. In the formula, multiply by 100 to convert the value into a percent: = (1-1/A2^2)*100 . Use cell A2 to refer to the number of standard deviations. Press Enter, and get the answer in cell B2. Round to the nearest hundredth, and the answer is 30.56%.
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.
Chebyshev's theorem is used to find the proportion of observations you would expect to find within a certain number of standard deviations from the mean.
Using Chebyshev’s Rule, estimate the percent of student scores within 1.5 standard deviations of the mean. Mean = 70, standard deviation = 10. Solution: Using Chebyshev’s formula by hand or Chebyshev’s Theorem Calculator above, we found the solution to this problem to be 55.56%.
In this video we discuss what is, and how to use Chebyshev's theorem and the empirical rule for distributions in statistics. We define both of these topics ...
Chebyshev's Theorem helps you determine where most of your data fall within a distribution of values. This theorem provides helpful results when you have only ...

19.04.2021 · Again, notice that the Empirical Rule provides exact answers while Chebyshev’s Theorem gives approximations. If you know that your data follow the normal distribution, use the Empirical Rule. Otherwise, Chebyshev’s Theorem might be your best choice! For more information, read my post, Empirical Rule: Definition, Formula, and Uses.
