Do not buy. It is trash. Overpriced, simplistic, inadequate and very poor app. A complete waste of money. There are many much better and completely free apps available. I wish I could get my money back.
Horrible Product As a huge fan of the original Wolfram Alpha and the Wolfram Alpha calculus apps I am utterly shocked at the abysmal quality and utter simplicity of this app. It is missing so much detail and options that a truly useful statistics tool needs to be worth the money I've paid. Utter twaddle. I want my money back.
This is a electronic reference book. Not an app calculator. It does not allow you to do custom calculations. Other apps similar to this will allow you to use example, go back and modify it with your custom data eeded for the test, and solve the equation.
Make this a training tool. One improvement I would press for is displaying the equation that is being used, which input value applies to which variable, and a brief visual on how the calculation is performed. Also. display the TI 83/84 and 89 function names, as well as, the Excel function names.
Handles elementary statistical calculations very competently It's fire.
VERY incomplete app. (1) We need more distributions. (2) In normal distribution (and others), we need a way to compute X given the percentile and the mean and the standard deviation. (3) We need also for the normal distribution (X, miu, sigma), not only for the normal standard distribution (Z), to compute percentiles.
