StatFun - Statistics functions for the TI-83 and TI-84

StatFun gives TI-83 and TI-84 calculators some additional statistical standard features from the later-model TI-84, TI-89, and TI-Nspire calculators, as flash-memory Apps or as programs. These calculators are approved for the AP Statistics examination. Hence older calculators may be enhanced with these functions for the AP Statistics examination.

Dots: Dot plot of a list

RandSamp: Random sample of list with or without replacement

InverseT: Inverse t distribution

Invχ²: Inverse cumulative χ² distribution

χ²GOF-Test: χ² Goodness-of-Fit

LinRegTInt: Linear Regression t-Interval

LinRegTIP: Linear Regression t-Interval with prediction

PDF documentation is included. This package is also available at ticalc.org. Example screens:
