In this lesson, students use data about the number of pairs of socks they own as an a springboard into analyzing data distributions. They initially have the freedom to make whatever visualization they want about the data, as at this point they should have learned about representations (boxplots, histograms, stem-and-leaf, bar chart, etc.) but they have not been explicitly recapped). Through their representation, they then answer questions about the symmetry, center, outliers, and spread of the data. After the eventual class discussion, we work through a notesheet about analyzing the Shape, Outliers, Center, and Spread (SOCS) of data, and they have an opportunity to analyze the SOCS of their socks using their calculator to assist them with some of the calculations.
Note that depending on your schedule and how deep you want your discussion to be, this lesson might not wrap up in one day. I make reference to this in the lesson plan.
