# Alpine Giant Slalom Skiing

## The crazy sport we have grown to love!

Giant Slalom Skiing is one of the oldest Winter Olympic events, starting in 1952. It is now one of the most popular Winter Olympic events with some of the most athletic competitors. This sport has truly taken over the world with Olympians coming from all over Europe and North America. Giant Slalom Skiing also happens to be one of the most watched Winter Olympic sports. It currently ranks number 4 behind Freestyle Skiing, Figure Skating and Snowboarding. It is no wonder why people watch this sport! With athletes as talented as Ted Ligety, you're sure to be watching the best athletes compete every 4 years!

## A Competion made by Passion!

This article was made to compare the performances of both Men and Women in a competitive way. In other words, this artcle was made to show the difference in performances for the gold medalists in the Men and Women's categories in order to determine which group is likely to beat the other's in athletic performance and in what Olympic year we are sure to see this take place in!

## The Main Goal

Although one group may dominate the other in one particular event (Such as the Women do in Giant Slalom Skiing), we are trying to determine which group of athletes times is increasing at a faster rate. In other words, which group of athletes times are actually getting slower. It is our job to find out what group will surpass one another and at exactly what time that will happen by using linear regression.

## Scatter Plot

Let the blue squares represent the Men and the red x's represent the Women. The data points on this graph represent the Gold Medalist times for Men and Women from 1952-2014.

## Linear Regression or Lines of Best Fit

Let the blue line represent the Men's line of best fit and the red line represent the Women's line of best fit. Since the Men's line has a positive slope, they are getting slower. Since the Women's line has a positive slope, they are getting slower. However, because Men are increasing at a slower rate, they are expected to be faster than Women after the intersection point.

## Analysis of Data

As shown in the data, Women have currently been beating Men. The data also shows that Women are currently increasing their times at a faster rate. The data predicts that the Women's times will be equal to the Men in the year of 2016 (X-Coordinate). The Graph shows that Women are increasing at a a faster rate and getting slower at Giant Slalom Skiing while Men are increasing at a slower rate and are getting slower at Giant Slalom Skiing as well. Because 2016 is not a Winter Olympics year we can predict both Men and Women to be slower in the 2018 Winter Olympics. However, because Men are increasing at a slower rate than Women, we can expect Men to be faster. We can predict the average fastest time in 2016 to be 157 seconds or 2 minutes and 37 seconds (Y-Coordinate). However, because 2016 is not a Winter Olympic year, we are expected to see the Men's times be slower than the Y-Coordinate and the Women's times to be slower than the Y-Coordinate, but the Men's gold medalist is expected to have a faster time than the Women's.

## X-Coordinate

The X-Coordinate represents the year that Men and Women competing in Giant Slalom Skiing will become equal in time taken to complete the course. This means that 2016 is the year that Men and Women will finally have equal times in Giant Slalom Skiing. 2016 may be the X-Coordinate on the point of intersection for Giant Slalom Skiing but 2016 is not an actual Winter Olympic year. The next Winter Olympics are in 2018.

## Y-Coordinate

The Y-Coordinate represents the time to complete the course for both Men and Women at the point of intersection. As shown, Men and Women will both be at 157 seconds or 2 minutes and 37 seconds at the point of intersection.
