IntroStat - Statistics Solver

That’s about my only issue but it’s a perfect app otherwise

Has a free textbook inside and intuitive functions

not only is IntroStat - Statistics Solver an outstanding probability and statistics calculator ideal for an introductory statistics couse, it's an exceptional value with detailed examples and explanations . . . moreover, the developer, zhiyi zhang, is remarkably helpful in illuminating difficult concepts

This app is an absolute life saver with statistics. If you’re a doctoral researcher or anyone who is in a statistics class, this app is a must have. Don’t waste your money of expensive programs or calculators when you can purchase the premium version of this app and have everything you need including a whole textbook!!

I have never written a review before, but I really want people to know how amazing this app is! It genuinely saved my life during my summer statistics class. It’s super easy to use and gives you all the information you need with no paid memberships or anything. I got tired of googling specific calculators for each individual problem and discovered this app which has all of them in one! It’s much easier to use than a ti-84 and gives great explanations. 11/10 recommend to struggling college students lol

Everything about this app is concise and helpful, it guides you along every problem and has so many resources and tools. Really glad to have this as a way of checking my work !

Very intuitive tool if you want to explore different concepts in statistics and probability. Easy to modify parameters and quickly see the results

A quite handy tool for introductory statistics! The whole package! Highly recommend it!

Wow! I’ve been waiting for an advanced calculator like this for my my phone and this gets anything I want done with ease. Godsend of an app!
