Quiz Day

Professor: "OK students, you have fifteen minutes to plot the bivariate distribution between A and B, fifteen minutes to compute the correlation between A and B, and 5 SECONDS to compute the kurtosis of B."

One student stands up very worried: "Excuse me Professor, how can we posssibly compute a kurtosis in 5 SECONDS?"

The Professor looks at the class very reassuring: "No need to be worried, kids, IT TAKES ONLY A MOMENT!!"
