Yup, CLuvsSoccer is right. It's some sort of scientific guess, that can provide an explain a certain phenomenon, or explain a problem. Say you have a certain problem that you need to solve. You have to guess where that problem originates. By considering the situation, you'll have several guesses on where might the problem come from exactly and solve it. In this case, you have developed several hypotheses and check them all. Once you pin pointed the problem, you can more easily solve it. Is it clear?
Hope it helped! :)
