I didn't think that I had to tip; now I think I should have. Any way to make this right? [more inside]

Ok, its homework help time! You'll probably groan at me to do the work myself, but believe me, I am. I'm just a little short of time, and textbooks and Google are not helping me. I'm analysing the data collected from my Physics coursework, and realised I need to know: Is the coefficient of restitution of two particles a measure of the percentage of kinetic energy retained after a collision? Or is it the energy lost? Or something else entirely?
