How Can We Sort Our Junk? Can You Roll Your Tongue? How Expensive Is Your Name? How Tall Were the Ancestors of Laetoli? What Do Frogs Eat? These are a few of the 20 data analysis and probability investigations in Bridging the Gap (BTG).

The module's investigations are written as guides for teachers to implement straightforwardly in their K-8 classrooms. Each investigation is based on the four-step statistical process as defined by the Guidelines for Assessment and Instruction in Statistics Education (GAISE):

  1. Formulate a question that can answered by data
  2. Design and implement a plan to collect appropriate data
  3. Analyze the collected data by graphical and numerical methods
  4. Interpret the analysis in the context of the original question

Each investigation contains:

A CD-ROM that contains activity sheets and other material is included for ease of making copies for classroom use.

Graphs are an integral part of data analysis. Those found in BTG include bar graphs, dotplots, stemplots, boxplots, and scatterplots. Statistical measures include those identifying center (mode, median, mean), spread (range, inter-quartile range, mean absolute deviation), and correlation (quadrant count ratio).

Students who have mastered these investigations will be prepared to pursue those at the high-school level as found in Making Sense of Statistical Studies (MSSS). MSSS is a module of 15 activities covering the Common Core State Standards in Statistics involving surveys, observational studies, and experiments.
