I've been immensely pleased to read these BBC articles recently, which go a long way to dispelling many of the misleading, ambiguous and outmoded stats and comparisons we trainers trot out.

Juliet, you might like this then!
Three professors — a physicist, a chemist, and a statistician — are in the common room when a fire breaks out in a wastebasket.
The physicist says, “I know what to do! We must cool down the materials until their temperature is lower than their ignition temperature and then the fire will go out.”
The chemist says, “No! No! I know what to do! We must cut off the supply of oxygen so that the fire will go out due to lack of one of the reactants.”
As the physicist and the chemist debate what to do, the statistician runs around the room lighting more fires.
“What are you doing?!” the physicist and the chemist scream.
The statistician replies, “We’re going to need a larger sample size.”
