Useful Equations for Statistics Students
Dont try to memorise this document.
Yes, I mean that. This is not something that you should try to read tip to cover. It does not substitute for your textbook.



It certainly isnt something to keep you company on the beach or in the ski lodge. Rather, its intended to swear out as a quick diagnoseence to the primary textbooks employ in statistics courses at the University of Phoenix. Specifically, it is currently designed to accompany the reticuloendothelial system/341 and RES/342 texts by Doane & Seward (2007) and the QRB/501 text by Lind, Marchal & Wathen (2005). When we change textbooks, I will update this paper to refer to the new textbooks.
