Middle School Statistics: Data Analysis

In grades 6-8, students learn to formulate questions, design studies, and collect data about a characteristic shared by two groups or different characteristics within one group. They learn to use graphical representations such as histograms, box plots, and scatterplots to represent data, and come to understand which representations most accurately present the data. They find, use, and interpret measures of center and spread, including mean and interquartile range, and they make, test, and use conjectures to formulate new questions and plan new studies to answer their questions.

Middle School Problems of the Week that approach questions from a statistical point of view are listed below. They address the NCTM Data Analysis and Probability Standard for Grades 6-8.
