Great for my intro stats class

This covers all the methods we learn in Stat 101, and is so easy. Our teacher even uses it in class to demonstrate a new analysis, and we can follow along on our phones. No more tables to look up to find P values, or what test statistic to use. Incredible easy!

Great Basic app

I wish the one mean app would round at least one decimal instead of rounding the margin of error to a whole number. Students can’t use the app on their homework.
