Useless. Constantly crashing
Can't load data. Worthless calculator if you can't load more than three numbers before crashing.
Charge in app, not good idea!
I need emergency to importdata! And do not have credit in my ID right now :(
Data set mgt upgrade not worth anything
Can't even tell how good this app is in practice as the only way to get data into it to type it in, despite having paid to import files. This should be fixed before charging for an upgrade. Also, sample data should be used to show capability.
Excellent Statistics Package
The TI 84, Casio Prizm, and Casio 9750 all have outstanding statistical capabilities. So does GeoGebra, the free international software for all computers. The apps in the app store have been limited. There are some good mathematics apps, and some good graphics calculator apps. But this is the first app I have found that begins to deal effectively with statistics. It really does a lot of things well. It handles distributions and hypothesis testing beautifully. I used to buy the CRC Handbook of Statistics, and this app covers much of that material. It does linear regression only, but I expect other regression models will be added. The handling of files is good if you spend the extra dollar. It's big strength is that you can make your statistical calculations anywhere, and email the results. None of the graphics calculators can do this. And, on the IPod Touch, it is really portable, and with you wherever you get a statistical idea. This is an extremely worthwhile app even if you use high powered software on your computer. In addition, formulas are given so that you don't just enter numbers and get mysterious results. It is an excellent app, well worth buying.

Does statistical analysis
Used it as a study tool for my stats class. Works great as a work tool, too.
It was money well spent.
