Statistics Collection
The statistics visualizations listed below were created with and, therefore, can only be viewed with The Geometer's Sketchpad. Once copied onto your computer, these sketches are dynamic in that you can manipulate portions of these graphs, including the data points.
You'll also want to have Sketchpad configured as a Helper Application to launch Sketchpad directly from your web browser and work with these sketches immediately.
