Alpine Slalom Skiing

By AnnaMarie Fernandes

Alpine Slalom Skiing

Alpine Slalom Skiing is one of the most popular events at the Winter Olympics. Winning in this sport is based on two things: speed and staying on course. The slalom uses the most technique of the alpine skiing disciplines. The person that is skiing or the skier must make his or her way through a course that contains a lot of direction changesand a series of poles, that are called gates, that are spaced close enough to force the skier to go in and out of gates in really tight turns. In this event the skiers don't use much speed but, the difficulty of going in and out of the gates sometimes throws the skiers off of the course. Skiers run through the course twice and the time for the two runs is added together to see who the winner is.

Reasoning

The reason for this article is to compare th Men's and Women's times for Alpine Slalom Skiing. I am only going to compare the gold medalists times over forty years. Now you(the reader) are going to find out who did better over the forty years, when they overlapped, what all of this information means and more!

The Goal

I am trying to find out who did better, the Men or the Women. Below you will see my data table of the time in seconds of the Men and the Women over forty years.

Scatter plot

Below you will see a scatter plot of the data. The blue squares represent the Men's Alpine Slalom Skiing Times and the pink x's represent the Women's Alpine Slalom Skiing times over the past forty years. Notice that the x's are lower than the blue squares most of the time, remember that the lower the time is the faster that they are going so the lower the blue squares and pink x's that means the faster they went.

The Linear Regressions or The Lines of Best Fit.

Below you will see a picture of a graph that has the lines of best fit on it. The red line represents the Female times and the blue line represents the Male times. Remember when I told that the lower the point are on the graph that means the faster time that they have. This also applies to the trend lines. So you can see that the Women did better on this event than the Men did based on the points and the trend lines.

The Intersection!

Below you will see a picture of when the line intersects. It was very hard to find this because the Men and Women hardly intersected. There was a clear separation between them. The intersection means when the Men and the Women had an equal time. I had to go back a long time to see this intersection. This intersection happened when the event just got started. It happened either on the first time this event was held or the second time this event was held. After this event was held maybe once or twice than everyone could see a clear winner the third, fourth, fifth, ect. time onwards.

The X Coordinate

The X- Coordinate means(in my event) the year that the event took place. So if you had to graph this on paper you would put the years on the x- axis.

The Y- Coordinate

The y coordinate in my event means what the times were, in seconds, that the Gold medalists finished. Is you were to graph this on paper you would put the times, in seconds, on the y- axis.
