For my linear regression class we need to come up with some kind of simple experiment (we must collect the data, can't get it online) for which we can use the methods we have studied in class (simple linear regression, multiple linear regression, ANOVA, ...) to analyze the data.
I am having the hardest time coming up with something. Anyone have a good suggestion?
Last year someone did something silly like compare how fast mustard descends an incline compared to ketchup.
EDIT: Thanks for all the helpful ideas guys :) I ended up with doing some physical experiments on myself on a stationary bike (max speeds/power output at different gear ratios). Probably not the greatest experiment, but it utilizes something I enjoy.
