Probability-Distributions

Subject line says it all. P(Z<x) for normal and a bunch more for essential statistical tests. THANK YOU!!!!

I love probability distributions.

Works perfectly now. Much better than using tables.

This could be really useful for students in college stats courses who are on a budget and can’t afford to buy a $100+ dollar graphing calculator. It does basic advanced functions like binomial pdf - for free. I don’t know if it does invNorm or Z-Test calculations ( possibly not) but for a calculation app that you don’t have to pay for this is pretty great and was just what I was looking for.

Easy my learning

I had Bognar as a professor multiple times in college and his app always came in handy. Whether on homework or studying for actuary exams, it’s always nice to have an app that can quickly compute values, in addition to showing graphs that help visualize data.

My professor created this for his students and I must say Professor Bognar is the juice cuz this works very well.

Love this app! Web app on hypothesis testing and confidence interval is even more useful, especially the version where raw data can be the input!!

Doesn’t try to do a lot, but what it does it does very well. Thank you for this app. (Future feature request, if you have time: Allow setting plot boundaries. e.g. for Beta, it’s sometimes illuminating to set the x bounds to (0,1).)
