Hypothesis

A hypothesis is an explanation that accounts for what you have observed. For example, if I note that there are holes in my cereal boxes, and I further see trails of cereal crumbs leading to a hole in the baseboard of my house, I might hypothesize that I have at least one mouse in my house. I am not stating for a fact that I have mice (perhaps it´s a different animal, or a series of odd coincidences) but I am saying that odds are, it´s a mouse. If further investation reveals new data - perhaps I notice that the holes are quite large, and that the trail of crumbs didn´t actually go all the way to the baseboard, I might revise my original hypothesis. I might surmise that it isn´t a mouse at all, but my dog. Hypotheses are working explanations that can be revised to explain new data, and are typically abandoned when they no longer seem to explain the data very well.
