Fathom, Dynamic Statistics Software, is a product of Key Curriculum Press.
Click the folder on the right for my earlier examples of Fathom files and resources for the teaching of data handling.

Fathom is primarily designed for dynamic data analysis, by providing tools to create and manipulate statistical and functional graphs, measurements, tables and simulations.  The dynamic features of the software, such as direct manipulation of data and inspecting cases simultaneously in different graphs and tables, support students’ exploration of data in an intuitive way.
