Great reference If you use stats and can't remember how to do something certain, this app is amazing. Though, as some people have mentioned, there are a few discrepancies/errors, so this app might need some revising. Still, it's mostly correct overall. It's best only to use it as a reminder or a quick reference - don't depend too heavily on it.

Blinking Ads? I don't object to ads in free apps; developers gotta eat, too. But I draw the line at flashing, blinking ads. I felt like I was trapped on AOL in 1995, and all the web pages were <BLINK>ing at me. This app could be useful, but I'd need to put a piece of duct tape across the top of my phone screen to avoid having seizures. UnInStAlLeD.

typos and mistakes The equations are mostly correct, but variable names are swapped. The text has the wrong descriptions for some variables. Example, in the formula y = a + bx, the text describes 'a' as the slope of the regression line, and 'b' as the intercept. Then, it calculates b as the intercept and a as the slope, so the equation y= b + ax is the correct equation.

Good ... but be careful As someone else has pointer out, there are mistakes. In the correlation coefficient example in section 5, the sigma y, and sigma xy, both have the wrong signs. The supposed strong -ve correlation is a strong +ve one.

What an excellent apps!!! So simple, easy to understand even for non statistics students. I hope you can add more statistics topics such as non parametrics, multivariate, etc.

Best app on stats basics that can take you whole way long..100 stars to the developer

Awesome!!!! This app has all the info needed to get you through when you feel lost. Great app with great examples!

I love the app!!!!! Thank you so much. With this, I now understand about the standard deviation and variance. Keep ur good work and God bless always!!!!

Informational app. Liked it. Good content but app crashes while viewing content under descriptive statistics.

Good Pretty basic stuff. I would prefer a more advanced stuff.

Soji Egbonwon Very useful app for getting the hang on statistics

Good effort for the subject... Doing a very good job keep it up....
