The Histogram-Area Connection
Gratzer, William; Carpenter, James E.
Mathematics Teacher, v102 n5 p336-340 Dec 2008
This article demonstrates an alternative approach to the construction of histograms--one based on the notion of using area to represent relative density in intervals of unequal length. The resulting histograms illustrate the connection between the area of the rectangles associated with particular outcomes and the relative frequency (probability) of those outcomes. (Contains 5 tables and 4 figures.)
