Bayes Rule in an animated gif · Simply Statistics
"Say Pr(A)=5% is the prevalence of a disease (% of red dots on top fig). Each individual is given a test with accuracy Pr(B|A)=Pr(no B| no A) = 90% . The O in the middle turns into an X when the test fails. The rate of Xs is 1-Pr(B|A). We want to know the probability of having the disease if you tested positive: Pr(A|B). Many find it counterintuitive that this probability is much lower than 90%; this animated gif is meant to help."
A GIF-Guided Tour of Remixed FiveThirtyEight Data
"Now that the UConn Huskies are the 2014 NCAA champions, and all of the win probabilities produced by our model are on GitHub, we decided to do some remixing of our own. We combined images of our probabilities at the end of each day of tournament games into a single animation that shows how those probabilities changed as the tournament played out.
