<p>I have Casio FX-9860G that I bought for my Honors Algebra II class this past school year. I really like this calculator, it's really easy to do all the Algebra II stuff, plus the standard deviation, and the percentages stuff. </p>
<p>However, this coming fall I'll be taking AP Stat and Honors Pre-Calc. Now according to my Algebra II teacher, she recommends Texas Instrument, don't remember which one. She said it's much easier to graph, and do Stats.</p>
<p>So what calculator do you recommend? Should I just stick with my Casio?</p>
<p>89-Titanium, but you'll need to customize it a lot and make sure it has Stats/List Editor (a port from the 83). I made a little toolbar to make everything handy.</p>
<p>However, if you are a non-calculator nerd, I would suggest a TI-84</p>
<p>Yeah, it takes a lot of experience with the 89 to make it completely usable with Stats, especially when you use a textbook that is customized for the 83/84</p>
<p>If you're doing 84+ vs. 83+, go for the 84+ b/c there are a couple extra stats functions that are rather useful (don't remember the exact ones--I think there was another useful chi-squared one that the 83+ didn't have). I don't have an 89, so can't say much about that.</p>
<p>84 has extra chi squared fns as well as linear regression t-tests, which although hardly ever come up, can be a pain in the butt, like on this years stats test.</p>
