This Instructional Activity is a part of the Lesson 8, Unit 6, Grade 6. The concept in this example may be challenging for some students. When Robert talks about the precision of the mean, Sabina asks him to explain what he means by a mean being precise. Although the means are about the same for the two distributions, Robert is suggesting that the mean of degrees for San Francisco is a better indicator of the city's typical monthly temperature than the mean of degrees is as an indicator of a typical monthly temperature in New York City.
