Facilitating the use of powerful quantitative tools requires that education be a critical part of our mission. We also feel strongly that the educational materials we have accumulated over the years be free to all who are interested. This belief extends to our software. All Wizards are designed so that in demonstration mode they can serve as teaching tools, and we encourage educators to use them for this purpose. Please feel free to explore this section and make thorough use of it. Also, you may want to take a look at our Learning Library. And let us know if there is something else you would like to see.
