In school I l earned how to use data and fair test. I had to see what bounced higher a ping pong ball or a super ball. I had to drop them with no force and I had to drop it from an eye level. When I did this I had a meter stick and my partner recorded how high each ball bounced. We took the number that show most often and that was the number that we would use for our data. Once when we collected all of the data we saw that the super ball bounced higher. But now we needed to know how much higher the super ball bounced then the ping pong ball. So now I subtracted the super balls data from the pingpong balls data. Now I was sure that the super ball bounced higher. :]
