Contemporary Curriculum Issues
Contemporary Curriculum Issues: Statistics in the Middle Grades: Understanding Center and Spread

Gary Kader, Jim Mamer 

August 2008, Volume 14, Issue 1, Page 38

Abstract:

Understanding center and spread in statistics is the focus of this issue's Contemporary Curriculum Issue. A lesson is described that involves formulating a question that can be answered with data, collecting data to address the question, analyzing the data and interpreting the results. The mean is viewed as a balancing point to discuss variability in dot plots and box-and-whisker plots.

This regular department provides a forum to stimulate discussion on contemporary mathematics curricular issues across a K-12 audience.
