## Reflection: Intrinsic Motivation Dispersion of Data (Day 2 0f 2) - Section 1: Partner Work

In this article, it posts how standard deviation is used to measure risks.  The entire insurance industry is based upon predicting these risks.  By showing students relevance in the real world, I think it hooks students, and provides them intrinsic motivation to want to learn.

Presenting students with some data for them to act as actuaries to provide insurance or not for customers with given information is a good extension activity for this lesson.  It may be something that the advanced students can focus on more, as teachers work with lower level students.
