#"An hypothesis is.............."#


An hypothesis is a proposed explanation for a given (and simple) phenomenon. A theory is a coherent group of tested general hypotheses and generally confimed propositions. A theory is commonly regarded as correct, and can be used as the basis of explaining new phenomena and new data.

And a variable is a point of data or condition that can be controlled in a scientific experiment.
