Document Summary

Must be related to and logically follow from your hypothesis. Null: hypothesis that there is no significant difference between specified populations; any observed difference being due to sampling or experimental error. Alternative: new theory w/several examples, and utilized until incorrect prediction arises: testing your predictions: Additional prediction could later be generated from the hypothesis and found to be incorrect: the never-ending possibility of an additional new prediction that could be incorrect means that hypotheses can never be proved. If found to only generate correct predictions for a long period of time, a hypothesis graduates to being called theory, an accepted explanation of how/why things happen. Theory: significant amount of experimentation has occurred that suggests explanation is unlikely to ever be found to be incorrect. Theory: can be incorrect, tested, less likely to be incorrect, accepted (because of the testing) explanation of how/why things. Invariable; states what always happens under certain conditions and doesn"t require testing.
