200 Meter Dash
The Speed, The Agility, The Track
The Goal of The Study
By analyzing, graphing, and interpreting past information from Olympics, the goal of this study is to find out when male and female competitors will be in check and when one gender will dominate another. Mathematical predictions, estimates and linear regressions will contribute to recognizing trends and patterns in the 200 meter dash.
The Data Table
The data begins in1976. The left hand column in the year, while the second and third column are times. The second column, denoted with a (M), are all the times of the male gold medal champions (200 meter dash) every Olympics from 1976-2012, while the third column is the times of all the female gold medalists from 1976-2012.
The intersection of both lines shows many important results, one of which included the year at which the estimated times for both the female and male gold medalists will be the same. Past this point the male competitors will dominate and before this intersection, the predicted result is that the female competitors will dominate. Both lines are not very steep meaning that the male and female competitors time is not a huge difference.
The x-coordinate, or independent variable in this case is the year because it doesn't depend on any other variable. According to the intersection graph, the year the intersection occurred was in 1838; the next Summer Olympics occurs in 1840 so around that year, the female and male gold medalists would have around the same time.
The y-coordinate, or the dependent variable is the time in seconds. The y-coordinate for the intersection is 46.39 seconds, meaning that in the year 1840, the next Summer Olympics, the male and female competitors' times would be around or almost equal to 46.39 seconds. After this intersection, the male competitors began to dominate by completing the 200 meter dash in a shorter time that the female competitors.
