This Instructional Activity is a part of the Lesson 12, Unit 8, Grade 7. In this activity, students think a little more deeply about the data we would like to know and how that compares to the data we can collect easily and quickly. They are presented with a statistical question that does not have an obvious answer. Students are then asked to consider ways they might begin gathering data to answer the question, but are asked to realize that the data they could reasonably collect is not everyone addressed by the question. Following the activity, the discussion defines the terms population and sample.
