Hello and welcome to Stats Coach!
As a student myself pursuing a data analytics major who also tutors business stats, I am passionate about helping other people enjoy statistics as much as I do! If if you do not use statistics directly in your day to day life, I hope these videos help you understand how statistics apply to the world around you... or maybe you're just here to pass the test tomorrow.
Either way, I hope you enjoy!
