Downhill Skiing
What is Downhill Skiing?
Downhill Skiing is a Olympic sport where athlete race down a hill. The racers have to make it past gates. If you don't miss any gates, and you have the fastest time then you win. There are normally 3 rounds and all your times get averaged together.
Men vs. Women
Men have been slower in this sport for a long time but not for long. There times are getting faster and faster every year. Women times have been getting faster.
Goal of the project
In this project our goal was to figure out who was getting better faster. We had to gather data of times and for men and women. After that we had to enter it into the calculator and make a scatter plot.
Data
The data starts in 2010. L2 is the male times, and L3 is the female times.

Scatter Plot
The squares are the male points and the plus symbols are the female points.
Linear Regression
This is a picture of the equations for the lines of best fit. The first equation is the line for men. The second equation is the line for the women. The womens line has also been made thicker so you can tell the two apart.
The Intersercetion
At the intersection the male and female points meet. This means at this point their performance should be equal. Both of the lines are decreasing. This means that they are both getting better over time. The thick line is the female and the skinnier line is the male. As you can see the males line is decreasing faster which means they are getting better faster. On the other hand the female line is not decreasing as fast. This means that they are getting better, just not as fast.
The X Coordinate
The X coordinate represents the year (ex: 2002, 2006, 2010). The X coordinate happens in 2007 which is not a year for the Olympics. The next winter Olympics would happen in 2010. This would be the year that men start doing better than the women.
The Y Coordinate
The dependent variable represents time. According to the intersection the time will be 95.81 seconds. This should have been the time for the gold medal of men and women. This should be a good prediction for the times.
