School Newspaper (Old)

Students extend what they've learned from Lesson 13 to compare two populations based on samples. This lesson introduces the idea that you can determine if there is a big difference between two populations by looking at the difference between the centers of samples and comparing the difference to the measure of variability. This lesson is designed for 90 minutes and may take multiple class periods to complete. NOTE: This lesson is outdated and will be retired. The new and improved School Newspaper can be found in the curriculum.
