Genial, aunque con una pega...

Cuando se selecciona la distribución geométrica la aplicación se cierra sola. Por lo demás funciona de maravilla.

Finally! A simple, free N(0, 1) calculator.

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

I met my wife because of this app. Needless to say I’m not happy and it’s this apps fault.

Works perfectly now. Much better than using tables.

Does advanced functions for free!

Some College Student from WA on

United States

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.

Nice

Easy my learning

So handy

United States

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.
