Scientific The Method Observation b4 you make a hypothesis you must have something to describe. Something physical, natural, real. Observe something to know it is real Hypothesis a wild/rough guess. How could this have happened? Possible explanation of what has happened. Explain how and why something has happened, do it well enough to make certain accurate predictions. Be able to say else will be found. HOW-WHY-PREDICT. Look at was has happened in the past < historical, not all experimentation. Make a prediction, and test the prediction, to prove it wrong, seldom goin to prove something to be true. Test against additional observation and data test your hypothesis with more observations. Reject Hypothesis - false Revise Hypothesis to change be true Retain Hypothesis - true Theory extremely dificult to prove (things could change by coming from a whole different angle test (disprove, modify, or keep) Fact or Law Not w/ how nature works TC Chamberlain 1910 Multiple Working Hypothesis so you don't overlook evidence Accuracy closest to correct number vs. Precision imply false sense of accuracy Occam's Razor K.I.S.S. keep it simple student the simpler the more likely you are to being correct
Correlation vs. Cause & Effect many people give correlation while implying cause and effect question it Absence of evidence vs. Evidence of Absence don't know Disagreement argueable w/ evidence vs. Controversy nothing against it, no evidence
