Back-to-back stemplot. The current major league single-season home run record is held by Barry Bonds of the San Francisco Giants. Here are Bonds’s home run counts for 1986 to 2007:

16 25 24 19 33 25 34 46 37 33 42 40 37 34 49 73 46 45 45 5 26 28 A back-to-back stemplot helps us compare two distributions.Write the stems as usual, but with a vertical line both to their left and to their right. On the right, put leaves for Ruth (Exercise 11.17). On the left, put leaves for Bonds.

Arrange the leaves on each stem in increasing order out from the stem. Now write a brief comparison of Ruth and Bonds as home run hitters.
