Worksheet, Discussion #20; Tuesday, 4/9/2019 GSI name: Roy Zhao Chebyshev’s Inequality Concept 1.Chebyshev’s inequality allows us to get an idea of probabilities of values lying near the mean even if we don’t have a normal distribution. There are two forms: P(jX j<k˙) = P( k˙<X< + k˙) 1 1 k2 P(jX j r) Var(X) r2:

This means that we don't need to know the shape of the distribution of our data. With only the mean and standard deviation, we can determine the ...

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 Theorem Definition Chebyshev’s Formula: percent of values within k standard deviations = 1– 1 k2 1 – 1 k 2 For any shaped distribution, at least 1– 1 k2 1 – 1 k 2 of the data values will be within k standard deviations of the mean. The value for k must be greater than 1.

Empirical Rule/Chebyshev's Theorem Worksheet 1) Adult IQ scores have a bell - shaped distribution with a mean of 100 and a standard deviation of 15. Use the Empirical Rule to find the percentage of adults with scores between 70 and 130. 2) Lengths of pregnancies of humans are normally distributed with a mean of 265 days and a standard deviation of 10 days.

The Empirical Rule is an approximation that applies only to data sets with a bell-shaped relative frequency histogram.

Interpretation: According to Chebyshev’s Theorem at least 81.1% of the data values in the distribution are within 2.3 standard deviations of the mean. You can verify that 2.3 is the correct answer by inputing it into Chebyshev’s Theorem Calculator above. You should get an answer of about .8110. Chebyshev’s Theorem Quiz – Test Your Knowledge
