stats! Statistics Learning and Decision Tool

Welcome to stats!, an app that provides an in-depth overview of many statistical topics, from descriptive statistics and t-tests to multiple linear regression and beyond!

The app contains information on the underlying concepts, mechanics and interpretations of the major tools of data analysis. When new (or even old) to statistics, it is often a challenge to determine the best test to run, given the question you want to answer and the data you have. This app offers a step-by-step tool to help you make these decisions! Appropriate for students from AP level statistics through undergraduate and graduate coursework, stats! hopes to make learning stats fun.
