For that reason, the estimate is conservative. We use the words “at least” when describing the percentage of data values. You will see the use of “at least” in the Chebyshev’s Theorem problems and answers given below. You can use Chebyshev’s Theorem Calculator above to see solutions to any problem you may have.

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.
