A good scientific hypothesis should explain beforehand what you expect the data to be if the hypothesis is correct. A good scientific hypothesis: "If I link 2 force meters together and pull on both, both should show the same force"
If the 2 reading are the same (within errors and repeated lots of times) then this supports the hypothesis. If I find a number of readings that are sufficiently different, they disprove the hypothesis.
