Description

Statmagic PRO makes intro stats simpler, clearer, and easier to learn. It has no ads or in-app purchases keeping you from full functionality.

PRO has all the functionality of the free version, plus:
> An exceedingly easy dataset import feature. Just open a spreadsheet in a spreadsheet app, copy the data onto your device's clipboard, and statmagic PRO can read it! And statmagic PRO can then help you select the correct test for your 1-sample, 2-sample, or paired data.
> An 11th calculator: the best-designed Chi-squared calculator out there. (Which, besides furnishing full test results, instantly calculates the expected and Chi-squared values when you enter the observed counts. Handles up to a 7x7 table.)
> In the regression calculator, PRO now gives you the ability to use the regression equation to calculate the predicted y for any chosen x. (And this y-hat is automatically plotted on the line, and also turns orange to warn you of extrapolation!)

> One- and two-sample tests of proportion (allows both decimal "0.48" and fractional "54/112" type entries for p).

Super simple and easy to use to work through various statistics problems. Now I don’t have to lug that bulky graphing calculator around!

Awesome!

This is a super useful little app. It’s going to make stat work a lot easier in future. I also like the clean look and intuitiveness of the design.
