![]() ![]() Here are some challenging practice problems that use Chebyshev’s Theorem. More Challenging Practice Problems Verified with the Chebyshev’s Theorem Calculator So now, the interpretation of the problem becomes: At least 84% of the credit scores in the skewed right distribution are between 100 and 700. Next, subtract and add 2.5 standard deviations from/to the mean, 400. Empirical Rule – used only for bell-shaped distributionsĬhebyshev’s Formula: percent of values within k standard deviations = $ 1 – \frac = 300 $$.Chebyshev’s Theorem / Chebyshev’s Rule – used for any shaped distribution.It’s important to remember that we only use the Empirical Rule with bell-shaped distributions. Teachers and textbooks often discuss Chebyshev’s Theorem and the Empirical Rule together. If you know that the distribution you are working with is a bell-shaped distribution, and you want to find the percentage of data values within 1, or 2, or 3 standard deviations, then you can use the Empirical Rule Calculator, a bell-shaped distribution percentage calculator. You can use Chebyshev’s Theorem Calculator above to see solutions to any problem you may have. You will see the use of “at least” in the Chebyshev’s Theorem problems and answers given below. We use the words “at least” when describing the percentage of data values. For that reason, the estimate is conservative. That means, we can use Chebyshev’s Rule on skewed right distributions, skewed left distributions, bimodal distributions, etc. ![]() That is, any distribution of any shape, whatsoever. So what is Chebyshev’s Theorem in statistics and what is Chebyshev’s Theorem used for? We use Chebyshev’s Theorem, or Chebyshev’s Rule, to estimate the percent of values in a distribution within a number of standard deviations. Then, try a problem on your own using the same strategy, then check your work with the calculator. The best approach is to first look at a sample solution to a couple different problems and understand the steps shown in the solution. ![]() You can use the Chebyshev’s Theorem Calculator as a learning tool. You don’t need the mean and standard deviation to use this calculator. Then, you will get a step-by-step explanation on how to do it yourself. The calculator shows you the smallest percentage of data values in “k” standard deviations of the mean. You can use Chebyshev’s Theorem Calculator on any shaped distribution.
