Statistics  Video Lectures Many students are also use our Statistics Lab Manual which loads into most spreadsheets. It is really a Quick way to learn. It is a stand alone but was designed to use with our free Quick Notes Statistics textbooks. This textbook had 90,000 free  pdf downloads during December of 2019. Hopefully, users did not have to buy a traditional high-price book. Thanks! Walter 11/28/22
