This Instructional Activity is a part of the Lesson 11, Unit 6, Grade 6. Remind students of the pairs of distributions from Example 1 and Exercises 1-6 that had the same means and how variability played a role in making decisions. Then, answer the question posed in the text. You have been comparing distributions that have the same mean but different variability. As you have seen, deciding whether large variability or small variability is best depends on the context and on what is being asked. If two data distributions have different means, do you think that variability will still play a part in making decisions?
