This Instructional Activity is a part of the Lesson 13, Unit 8, Grade 7. In this activity, students attempt to recreate the data from the population data using three given samples. It is important for students to recognize that this is difficult to do and that some samples are more representative than others. Without knowing the population data, though, it can be difficult to know which samples will be representative. Methods for selecting samples in an unbiased way are explored in future lessons.
