Maybe you have a baby that's a little underweight (what exactly does that mean) and then they gain some weight. Was it effective? Maybe they gained 1 lb when they should have gained 2 lbs. There's a problem in the CMP2 curriculum that uses histogram data to represent change in weight-of-backpacks before and after an assembly. It's quite difficult to see the change with histogram data, but with a box-and-whisker plot, it'd be a lot easier. Effective data representation is HARD. We don't teach it a lot in school, and so as a society we don't have a good grasp of it. Pragmatic On 4/29/08, TexasTeach2 wrote: > In what industry are Box and Whisker Plots used?
