Mikhail recorded the heights of all the male students in his math class. The results, in inches, are: 52, 55, 56, 60, 53, 51, 64, 67, 61, 58. Which type of graph would best display the heights in the 50 to 59 and the 60 to 69 inch range for comparison?
Solution: Stem and leaf plot would best display the heights in the 50 to 59 and the 60 to 69 inch range for comparison.
Stem-and-leaf plots are a method for showing the frequency with which certain classes of values occur. The stem and leaf plot is used like a histogram; it allows us to compare data. While a histogram uses bars to represent amounts, the leaves of the stem-plot represent amounts.
