This Instructional Activity is a part of the Lesson 2, Unit 6, Grade 8. Data collection is an important part of any statistics unit. Here, students collect data about a partner using the appropriate tools and submit the data for future use. In a lesson later in the unit, students analyze the class data they collect here using the methods they learn in the next few lessons. A copy of the class's data should be kept. It may be convenient to set up a shared spreadsheet if students have access to Internet-enabled devices.
