Chebyshev's Theorem
Chebyshev's theorem is used to allow you to understand how the value of a standard deviation can be applied to a data set. Chebyshev's theorem is used for research design and for statistics. The theorem states that for any sample, the proportion of observations, whose z score has an absolute vale less than or equal to K is no less than (1-(1/k²)). This came from the following website and you can go there for more information: http://www.gseis.ucla.edu/courses/ed230a2/chebyshev.html .

Chebyshev's Theorem A mathematician named Chebyshev came up with bounds on how much of the data must lie close to the mean. In particular for any positive k, the proportion of the data that lies within k standard deviations of the mean is at least...

EPA statisticians have recently proposed using Chebyshev's theorem to develop confidence intervals for the means of distributions. Chebyshev's theorem is properly a statement about moments of a distribution, so this is the right place to discuss it.

The method presented avoids the overly wide ranges commonly associated with the use of this theorem, and, being based on Chebyshev's Theorem, does not depend on the normality or specific form of the underlying distribution.
