Bell curves

This is a really good app to save money with. Graphing calculators are super expensive and you probably wouldn't need later on in life. It's best to use if you specifically need to calculate bell curves. However, that's just the whole function of the app - nothing else. Still super helpful and accurate though. It can be a potential of saving a lot of money.

Great Statistics App to understand a PDF and a CDF

Great Statistics App to understand/ teach the PDF and CDF concepts. Easy to import data. App helps you understand and visualize what happens to the PDF and CDF if you gradually change the mean, sigma, etc. A very simple App but enlightening.

Great Side App

This app is not for everyone. While it looks confusing and the scope may seem narrow it does exactly what it needs to do and is a very nice tool to keep by your side if you do not have a high end TI calculator. I wish it allowed more log functions, but is a great app none the less.
