I just got a TI-83 and it reminds me that I fell off the TI educational (not hacking) list. Anyone know how to rejoin?
By the way, the info on fitting curves to data in the TI-82 and TI-83 (they're completely different examples) manuals are excellent worked examples in curve fitting. They don't explain much about the statistics, and they talk funny (evidently the 82 fits data to curves rather than the other way round), but they do the right things -- even more things in the 83 manual.
Oh, though this section of the 83 manual talks OK, elsewhere they discuss the "Inner Quartile Range", presumably to distinguish it from the Outer Quartile Range. (I think it's an obscure measure used in navel research.) They really ought to have a statistician proofread their manuals.
