I work through a 2 sample mean t-test and a 2 sample mean t-interval using a TI-NSPIRE. The video starts with a description of the setting, hypothesis statement, and conditions check. Why? Because the numbers out of your calculator mean nothing if you can't do the test in the first place!!!
In this series, the very helpful and fun math teacher Mr. Rob Tarrou teaches students everything they need to know to get a 5/5 on their AP Statistics exam by the College Board. His videos are friendly, easy to understand, entertaining, and very well organized, all thanks to Mr. Tarrou great dedication to teaching and enthusiasm for mathematics
