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.
Co. Authors: Laura Kniffin and Kendra Wheeler.
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.
