The World’s Fastest Men Is there a pattern to the times for the gold medalists in the men’s 100 meter run from past Olympics? If there is a pattern can you predict the winning time for the 2008 Summer Olympics in Beijing? You’ll need to make a scatter plot to see if there is a pattern in the relationship between the year of the Olympics and the gold medal winning time. This scatterplot is easily created by hand. Let X represent the years. What will your domain be? Let Y represent the time of the 100 m dash. What will your range be? The World's Fastest Men and Women Steps Year Name Time(sec) 1.
