After you look at the data, think! 

The statistician Abraham Wald  worked on war problems during WWII. Asked where extra armor should be added to the airplanes, Wald studied the location of enemy bullet holes in planes returning from combat. He plotted the locations on an outline of the plane. As data accumulated, most of the outline filled up. Put the armor in the few spots with no bullet holes, said Wald. That's where bullets hit the planes that didn't make it back. (Based on Moore, 2004, p. 81)
