Gianna plotted these points and then connected the points in order from J to N and then back to J to show the shape of her room. Draw the room on the coordinate plane. What is the area of the room???

J: (1,0) K:(1,6) L:(9,6) M:(9,3) N:(6,3)

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
