Learn Statistics & Probability

Whether you're just brushing up or learning from scratch, this is a well organized crash course on Statistics. Provides a solid foundational baseline in a well organized format. Integration of interactive "active content" (e.g. Dynamic models/graphs, animations, etc. ) directly in the App itself would significantly increase effectiveness. However at this price point it exceeds expectations.

I downloaded many of the stats apps and this one is BY FAR the best; easy to understand, and super helpful!

It is an excellent statistics tutorial. It lays out both frequency and probability statistics in separate sections. The first $2 purchase only gives you the intro. To see it all costs a lot more with in app purchases. I hate that kind of bait and switch garbage, hence the low rating.

This app demands your full name and email address before you can use it. They hide this fact from you until AFTER you download the app. The app is disabled if you refuse to provide that very personal and private information. If you value your privacy, avoid this app and vendor.

Do not buy any Simple n Easy reference book apps. If you have already, do not update your app. If you do, you will be forced to register with your full name and email address before being allowed to open the book. This is totally unsatisfactory.
