THE BEST STATISTICAL ANALYSIS PACKAGE EXCLUSIVELY ON IOS!
Stats Pad LE brings detailed statistical analysis to your iPad and iPhone.

Stats Pad LE (light edition) allows you to get some of the analysis options available in Stats Pad full version for free, with the ability to purchase individual analysis packages for a lower price through in-app purchases. If you want all of the features available, the most cost effective option is to purchase Stats Pad full version also available in the app store. PLEASE READ THE LIST OF ANALYSES INCLUDED WITH THE LE VERSION CAREFULLY.

With over 60 different analyses (many available through in-app purchase) and growing, Stats Pad is the most complete analysis package you can get in this price range.
