I found this cool statistics app for the iPhone. It is called iStatistics. It allows you to create your own worksheet, do combinatorics, statistics and probability and linear regression. You can see screen shots at:

This app definately makes statistics fun ! The only thing it is missing is the ability to graph data points in the modeling section. It would be nice to see correlation between your data.
