Data Analysis
Data Analysis
addresses approaches to measures of center (mean, median, mode) and how they describe a data set. Students often use the algorithms associated with mean and median without fully understanding the ideas. When reasoning about data, they often attend to single cases and fail to observe characteristics of the aggregate, such as measures of center, as describing or representing the data set.
Professional Development Goals
 Listen for and support deeper understanding of measures of center and descriptors of the aggregate
 Review a range of graphic representations and their applications
 Explore reasoning about data aggregates through indices of data, different graphic representations, and an interactive tool
