1. Great, easy to use app, comprehensive and flexible - already one of my favourite apps!Wonderfully implemented, ads-free, flexible, and easy to use!Useful since I dont have a graphics calculator, however it isn't super user friendly (no text wrapping for answers, answer goes offscreen for "both tails" mode).
2. Could be a setting but I can't use for my class because I need 4 decimal places.Thank you! I was on the verge of tears trying to find the right calculator/app to solve the problems I had and this one doesn't it perfectly.
3. It gets more practical use than you'd think, even if you spend more time with applied stat than with theoretical.You can calculate probabilities on a distribution by inputing numbers or dragging points on the graph.
4. Highly recommend as an instructional tool if you teach or study statistics.I really liked this but maybe allow for more decimal places.
5. I believe this tool would be great for developing intuitive evaluations of distributions.Excellent expository app.
6. Excellent tool for calculations and understanding distributions visually.
7. There are a lot out there that claim to calculate probability and z scores but they dont.
8. This one actually works, though I don't think it figures out z scores, but I know how to do that on my own.It's awfully convenient having these on hand.
9. I'm just glad there arent that many invNorm or normalCDF questions to study.
10. so usefulOMG! FINALLY! A probability calculator that actually works.
11. Overall pretty useful anyway, made my life easier.so simple.
