I don't normally play soccer, but I still enjoy kicking a ball around and watching the game and it always amazed me how the players can make a goal from far away or even miss a goal up close.
So I was wondering, does the distance from a soccer goal (feet) depend how many goals you can make out of 5 shots from 30 different areas?
My brother will be taking shots from close in and working our way back to 30 feet out with five shots from each spot for a total of 150 shots.
My two variables are percentage and distance (feet).
I will record this data with my brother and I this weekend while we are at the soccer field at oxbow.
I believe it will be a negative association with a strong linear association.

THE FOLLOWING CHART INCLUDES THE CORRELATION COEFFICIENT

THE CORRELATION OF DETERMINATION IS 64.59%

THE LEAST SQUARE REGRESSION EQUATION IS 101.70 - 2.64 WHICH MEANS FOR EVERY FOOT AWAY FROM THE GOAL, THE PERCENTAGE GOES DOWN 2.64, IT MEANS I HAVE 2.64% CHANCE EACH TIME TO MAKE A GOAL

THIS CHART ABOVE IS BETTER THAN THE CHART ON THE TOP BECAUSE THE RESIDUALS ARE SO SMALL, THE POINTS ARE CLUSTERED AROUND THE CENTER RATHER THEN SPREAD OUT LIKE THE CHART ON THE TOP. I USED THE RECIPROCAL OF MY DISTANCE TO MAKE THE TRANSFORMATION FROM THE GRAPH ON THE TOP, TO THE GRAPH ABOVE.

LURKING VARIABLES- Some things that could have messed up my data was fatigue, my brother took shots one right after the other, so taking all those shots in a row, mixed in with chilly weather, could have caused him to become tired and less accurate as the shots got further away from the goal.


DATA ANALYSIS-

my hypothesis was incorrect. The association was positive with a moderately strong linear association while I thought it would be a negative association. I thought that the further away from the goal you got, the harder it would be to make a goal, and that was correct as you can see from my data. The correlation was 64.59 % which proves my hypothesis to be incorrect because the correlation indicates that is was actually positive, not negative.
