This Instructional Activity is a part of the Lesson 14, Unit 8, Grade 6. In this lesson, students begin to notice how the distribution of data affect the mean and median of a data set. Using their class height data, they examine how both measures of center are affected when a value that is far from the center is added to a data set. Students find that adding these unusually large or small values pulls the mean up or down while having little or no effect on the median.
