I took stats this past semester; I learned the TI calculator is your friend if you know what key sequence to use.
I spent a few hours a week perfecting my knowledge of the calculator and sadly it's all gone now after I got my passing grade, my brain e-dumped all the stuff.
Oh hell yeah. I would have shot myself by now if i didnt have my TI 83+
It makes it go a lot faster. the problem is my instructor just assigns a
load of homework. Its not that its hard, its that its long, and tedious. I have had to relearn to use my calculator since the last time I used it was an algebra class two years ago. It is damn handy though now that I am getting the hang of it again. Amazing little calculator.
