▷Statistics & Probability Made Easy - Step by Step - using the TI89 Calculator
(S.P.) "I have both SPME and Equation Solver and, to me, are some of the most useful software I have ever owned. I am an owner of a marketing consulting firm and work with two universities and their MBA programs (Quant. Analysis and Statistics courses for Marketing executives) and the software is easier to use and more intuitive than Excel. In addition, the support is industry leading. I have inquired many times for help and the step by step problem solving that was provided is a value add that exceeds the costs of the programs by many times. Support like that in today's world is unheard of. It is as though they wrote the software for me. I intend to purchase Accounting Finance Business Made Easy in the next few weeks."
