This Instructional Activity is a part of the Lesson 11, Unit 8, Grade 7. As a general rule, we will consider it a large difference between the data sets if the difference in means is more than twice the mean absolute deviation. If the mean absolute deviation is different for each group, use the larger one for this calculation. For students who ask why twice the MAD is used rather than some other value, defer the question for later in the unit.
