## Reflection: Staircase of Complexity Spread Out - Section 1: Opening

I really like the way these tasks unfold as they first ask students to do their own ranking of 4 sets of data from least spread out to most spread out. Next, students look at three different ways to rank the data and compare these methods to their own ranking.  I have found that following this sequence of activities leads to high student interest in standard deviation and helps them develop a strong understanding of the concept.

Unit 5: Data and Statistics
Lesson 8 of 14

## Big Idea: How would you determine how spread out a data set is? Students put data sets in order from least to most spread out based on their own intuition and reasoning.
