Animation: To Brush Or Not To Brush (Type I Error)

A 5-panel gif animation than can be used in discussing setting up null and alternative hypotheses and the concept of a type I error. The idea for the animation was provided by Dr. Karen Banks from Indiana University and received second place in the 2015 A-mu-sing contest. The idea for the final panel of the gif (regarding Type I error) came from the participants at a breakout session on the use of cartoons and songs in teaching statistics at the 2015 U.S. Conference On Teaching Statistics. The cartoons are drawn by British cartoonist John Landers (first of two animations arising from the USCOTS session).
