Christensen Stat Modules

For anyone trying to learn basic statistics or refresh forgotten knowledge, I freely provide the following online instruction modules for your use. I also recommend you consider purchasing one of Mario Triola’s Elementary Statistics books to give you access to practice problems. You can buy a used text on Amazon or eBay for only a couple of dollars. Pretty much any edition will do. Feel free to contact me or visit if you have any questions.
Kind regards,
