This plot shows the top 20 final times for the two-man bobsled teams at the 2010 Winter Olympics.

stem leaf plot 6

3:26|65 represents a time of 3 minutes 26.65 seconds.

As you can see the difference between the gold medal winner and the bronze medal winner is less than 1 second (3:27.51 – 3:26.65 = 0.86 sec)!
