Is there data to go with this?
Choose a sport.
In that sport choose five athletes where you compare their height to performance or weight to performance.
When your choice is made, graph your data, find the correlation coefficient, and explain the type of correlation found.
Provide the name of your sport, the athlete names, the type of data, the correlation coefficient, and a quality explanation of the correlation found.
Well, if I was making the data I would make a nearly perfect fit to make my life easy
But you can look up athletes weight and heights online.
However, performance can be taken many ways.
You can use batting average in baseball and their height or weights...
At ESPN you can see their stats...

You can measure their performace via batting average, on base percentage, or slugging percentage...
Likewise with pitchers you can use their ERA, earned run average.
