Even though men and women don't compete against each other in the 1500m dash, we can still reach conclusions about what the results would be if they did race.
The Goal of The Study
The date begins in 1976. List 2 is the men's gold medalists finishing times and List 3 is the women's.
The data continues.
Still more data
The data is still going on.
Linear regression (lines of best fit)
The red line represents the trend of the women's times for the 1500m dash and the blue line represents the men's trend.
At A Crossroads
The intersection point of the 2 trend lines is very important to our study. It shows when one gender will surpass another, or in this case, when the men surpassed the women. According to the trend lines, the men surpassed the women in 1896 which, incidentally, was the year the 1500m dash became an Olympic sport. The blue(men's) line which is decreasing indicates that the men's times are decreasing, or getting faster. The pink(women's) line which is increasing indicates that the women's times are increasing, or getting slower.
The x(independent) variable is 1896, which means that the men surpassed the women in 1896, which is an Olympic year.
The Y(independent) variable is 228.97, which means that the men surpassed the women with the time of around 3.82 minutes. That is pretty fast seeing as the record for fastest is 3:26.
