Statistics Calculator++

There is a few improvements but big one would be for you to swap input scores.

I was able to quickly and easily find the area under the standard normal distribution curve between my two values and so I can follow along with my online classes easily. This is worth the small price of $2, especially if you are serious about learning statistics anyway.

I bought this app expecting full features that I could use WITHOUT having to pay a second time. I just wanted to see what my line of best fit would like like when graphed, but I have to pay for that! You guys already make us pay for an app that, at first, is quite confusing. Why should we pay for more?
