10.2 The Olympics

10.2 The Olympics
<
>
  • Math Help

    In Example 3, note that the 1932 winning time is an outlier. Recall from Section 9.2 that an outlier in a data set is a value that is much larger (or smaller) than most of the other values in the data set. Also, note the gap in the graph from 1936 to 1948. The Olympics were not held during this time due to World War II.

    Here are some other reasons for the improved times.

    • More aerodynamic skating suits were developed.
    • The use of "artificial" ice. Machines were invented to make ice for the tracks, which provided a consistent surface for the skaters to use.
    • Skating on indoor tracks. With outdoor tracks, the skaters had no protection from the wind (and other weather conditions), which could adversely affect their times.
  • Consumer Suggestion

    Check out this video by TIME Magazine which shows speed skater Apolo Ohno training for the 2010 Winter Olympics. You can watch more videos from the 2010 Winter Olympics at TIME.com

  • Checkpoint Solution

    Enter the data into a spreadsheet and make a scatter plot.

    In general, the winning times for women's 1500-meter speed skating have decreased over the years.

    World Wars led to the cancellation of the 1916, 1940, and 1944 Games. Large boycotts during the Cold War limited participation in the 1980 and 1984 Games.
