Introduction to sampling

During World War II, a statistician by the name of Abraham Wald was asked to help the British air force decide where to put extra armour on their planes. They gave him charts of the bullet holes in planes that were wounded in fighting but made it back safely to England. Students are given an example image of planes, with each dot representing places hit by bullets and they need to decide where to put extra armour. In this activity, you should pace it initially to slides 1 and 2 and only show slide 3 when they have all completed it. This is more interesting to do if they don't have an opportunity to google it so you may wish to do it in class and just get them to vote on paper.
