200 Meter Butterfly
Linear Reg Project- Veda Velamuri
So... What is the Butterfly Stroke?
The butterfly stroke is much more difficult and complex compared to the other strokes swum at the Olympics. This is because it requires well built muscles and "on point" technique. The butterfly stroke is also the newest type of stroke swum at the Olympus, having both arms move at the same time like a breaststroke and followed by the butterfly kick.
Why am I on this page?
This article has been written to inform you about the 200 m butterfly stroke swum at the Olympics. You should know this because the butterfly stroke is the most fabulous of them all, and Michael Phelps won a gold medal in this category, making it even more fab.
What's the point of this?
The purpose of this project is to see the difference between men and women's times' in the 200m butterfly stroke for the past 40 years. The goal is to also find the year where both genders will have the same average amount of times.
Data Table Part 1
This picture shows the data of the gold medalists, men and women, according to the year they won. 1972- 1984 are the certain years represented here.
Data Table Part 2
This is the same kind of data table as the one before, but shows the years 1988- 2000.
Data Table Part 3
This picture shows a data table, just like the ones above, but has the data of years 2004- 2012.
Scatter Plot
The picture shown to the left is a scatter plot of all the men and women's times for the past 40 years. The pink X's represent the women's butterfly stroke times and the blue squares represent the men's time.
Linear Regression
This graph, showing the average of all the men and women in two different slopes, represents the time of 200m compared to each Olympics year. The graph can help clearly show the average time for both genders and what could happen in the future. Women are represented by the red line and men are represented by the blue line.
Intersection Point
The picture above shows the intersection point, which is where the men and women butterfly stroke times will eventually be the same. Even though this prediction may not be entirely true, it helps us see what the times would look like eventually.
X- Coordinate
The X coordinate on the graph and table represents the year. This means that all the numbers and coordinates are the years in which the Olympics took place over the past 40 years.
Y- Coordinate
The Y coordinate represents the amount of time it took for both men and women to swim a 200m butterfly stroke. On the graph it shows two separate lines of points for the two groups of genders competing in the Olympics.
