100m Breaststroke
By: Sarah Dubey
The Breaststroke
The breaststroke originated in the Stone Ages. It was the original way of swimming, resembling the way of a frog. The first Olympic breaststroke event took place at the 1904 Summer Olympics in St. Louis, Missouri. It has changed over many years, but this technique includes the swimmer laying face down in the water, with arms extended straight forward and legs straight backward.
Goals
My goal is to gather the fastest Olympic times for men and women in the past 40 years (10 Olympic games). Using these times, I will find the regression of men and women. I will put the information into a graph, and using the lines of best fit, I can find the year that women's times may be faster than men's.
Data
Gold medalist times of men and women in years 1976, 1980, 1984, and 1988.
Data
Gold medalist times of men and women in years 1992, 1996, and 2000.
Data
Gold medalist times of men and women in years 2004, 2008, and 2012.
Linear Regression
These are the lines of best fit, or trend lines. The red line represents the trend between females' times. The blue line represents the trend between males' times.
The Intersection
The intersection of these lines shows that women might have faster times than men in 2229, and that those times will be around 30.34 seconds. Since 2229 will not be an Olympic year, this would occur in the Summer Olympics of 2232.
The X Coordinate
The X coordinate represents the year. It is the independent variable.
The Y Coordinate
The Y coordinate represents the time in seconds. It is the dependent variable.
