Statistics: Graphing and Histograms

Today, Deb led the Stats class.  She reviewed linear regressions and one variable stats  she introduced normal distribution graph, how to shade, and how to clear shading.  Then, she used this data for Utah and Florida--located in this packet to show the class how to create population pyramids as good examples of histograms.   BTW, population pyramids are key topics in Human Geography and AP Environmental Science.  The class discussed the implications.  For example, there will be more demand for infant diapers in Utah and adult diapers in Florida.  The point is to differentiate between a bar chart of M&M candy colors and a population pyramid double histogram.  One can draw a number of inferences regarding future growth, its shape, etc.  Below is an example from one of the kids.
