This Instructional Activity is a part of the Lesson 17, Unit 8, Grade 7. In this activity, a dot plot is created by the class that includes all of the calculated sample means. Students then compare that display to the data from the entire population to better understand the information that can be gained from a sample mean. In the discussion that follows the activity, students look at similar displays of sample means for samples of different sizes. Students should see that larger samples tend to more accurately estimate the population means than smaller samples.
