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.

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.

I can rate this app 6/5...... Its such an awssome app that i can rate even +10 with full 5 stars.... ultimate job done by the developer..... hats off!!!!

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.

User reviews

Great tool for learning and for reviewing Absolutely loved the fact that the examples and definitions were consise and meaningful. Another thing that was glorious was the fact that the explanations were constructed using proof language! This is great not only for statistics, but also for a lite review on set theory, conditional logic, and proof construction! P.s this got me aroused.
