Visual & Statistical Thinking: Displays of Evidence for Decision Making

Visual & Statistical Thinking: Displays of Evidence for Decision Making

This is really a booklet, a reprint of a chapter of one of his books, and is a great way to get started on the way he thinks. It explores how graphics were used to track down the source of a cholera epidemic in London -- and how bad chart-making and graphics could have led to the wrong conclusion. The second example in this excerpt explores the explosion of the space shuttle Challenger. In this absorbing example, Tufte takes the 13 pages of (badly organized) data that the engineers debated on the night before the space shuttle was scheduled to blast off. Tufte first tears apart the charts, and demonstrates why even though the engineers reached the right conclusion (don't launch), why the data was presented so badly that NASA overruled them (resulting in the Challenger explosion). Then, Tufte rearranges the same data into a couple of clear graphic displays that demonstrate they clearly had enough data to demonstrate that the launch of the Challenger was clearly occurring at grave risk. A great example of clear thinking at work.

OK, so maybe great graphics won't save the world. But this is a good, well priced introduction into Tufte's line of thinking. If you think you might like his stuff, buy this; get hooked; buy the big books.
