Proven to Increase Learning & Motivation

The “Statistics 1” app has been tested in Introductory Statistics classrooms and is proven to increase learning and motivation.  We co-authored an Educause Quarterly article summarizing a 2-year research program evaluating the app.  Findings were overwhelming positive.

The “Statistics 1” app was developed by Ph.Ds. that took Intro Stats and sympathize with students. We know that learning stats is like learning another language. This app was designed to be the perfect tool for anyone looking for an inexpensive and always available tool to help you learn and understand intro statistics.
