# It needs to be able to do basic statistics operations.

It should have the ability to enter data into lists, assign values to variables (mean, standard deviation, sample size, confidence levels, etc.), be able to preform Z, T, chi-square, and linear regression tests, construct confidence intervals, do regressions, and really anything that a TI-89 can do. It's much easier to use a computer than my calculator, but there are no easy-to-use statistics calculators on the web.
