Okay so i handed out 30 surveys today. For each question I am going to write out the answers, and the percentage of people who answered that.

So, say 15 people listen to music more than three hours a day. I know that is 50%, but if the number was weird, like 8, how would I figure that out?

I have heard of some sort of theory that negative numbers are greater than zero. Can someone tell me the name of this theory and explain to me how this could possibly be true? Links would be great too.
