This learning packet reviews new terms and definitions, how to interpret and understand standard deviation, defines the empirical rule, Chebyshev's Theorem and gives examples.

A compilation of videos, power points, and text. We include step by step walkthroughs of finding standard deviation by hand and using a graphing calculator.

Tutorial

** Variance:** Is the measure of the spread, also known as the dispersion, of a set of data

** Standard Deviation:** The amount that data deviates from its mean. The percentage of probability that your data will fall within.

** Bell Curve: **The symmetrical curve of a normal distribution

** Chebyshev's Theorem: **A theorem used when you have a non-normal distribution.

** The Empirical Rule: **A rule used when you have a normal distribution.

__Note: __In the power point we more thoroughly go through The Empirical

Rule and the Chebyshev's Theorem.
