When I look at the analytic data for my blog, I notice a lot of people come here after Googling "stats memes" or "math memes" or "statistics humor". Being a data-driven sort of human, I have posted my collection of memes inspired by teaching Introduction to Statistics using SPSS. They do reflect common mistakes/stumbling blocks that I see semester after semester. I think they draw student attention towards commonly-made mistakes in a way that is not threatening. And it puts me one step closer to my ultimate goal of teaching statistics using nothing but memes and animated .GIFS
