The accompanying graph is a special histogram with additional information; it was made using StatCrunch. People who studied music as children were asked how many hours a day they practiced when they were teenagers, and also whether they still play now that they are adults. To understand the graph, look at the third bar (spanning 1.0 to 1.5); it shows that there were seven people (the light red part of the bar) who practiced between 1.0 and 1.5 hours and did not still play as adults, and there were two people (the light blue part of the bar) who practiced 1.0 to 1.5 hours and still play as adults. Comment on what the graph shows.
What other types of graphs could be used for this data set?
