Students learn the formula for standard deviation. This package consists of the following:
1. Students are given different sets of numbers. They find the mean, variance, and standard deviation of each set. There is a fully-explained example followed by 8 problems.
2. Students then compare the consistency of runners and football teams in the second activity. They are taught what the spread of data actually means.
Along the way, students can use a template created to help with the computations. Of course, the activities can be completed without the templates as well.
Added March 2015: A step-by-step Excel lesson is provided to show students how to use a spreadsheet to simplify calculations of standard deviation problems. No prior knowledge of Excel is necessary to complete this lesson!
A complete answer key is provided.
