This Instructional Activity is a part of the Lesson 7, Unit 6, Grade 6. Students read the introduction to the lesson. In Lesson 3, Robert gave us an informal interpretation of the center of a data set. In Lesson 6, Michelle developed a more formal interpretation of center as a fair share mean, a value that every person in the data set would have if they all had the same value. In this lesson, Sabina will show us how to interpret the mean as a balance point.
