Reflection: Developing a Conceptual Understanding Dispersion of Data (Day 1 of 2) - Section 1: Warm Up

 

Standard Deviation is an important concept when presenting the Spread of the Data.  I have found a simple way to present standard deviation in the video below by the AP Stat Guy.  I present the method myself, but you could show the video as well.  

He presents it in a simple, straight forward way with low numbers.  I think it helps students not only develop a conceptual understanding standard deviation, but increases the rigor when they do understand the meaning behind the formula.

The students will use technology most of the time to find standard deviation, but I want them to have an understanding of the concept.
