Document Summary
Accept claims only after researches have subjected them to careful scientific tests. 6 principles of critical thinking: rule out rival hypothesis. E. g. in group 2 flashing lights on/off and turning on alarm during a test. Variables could have been lights or alarm or both. Therefore, you have to test each variable individually: correlation vs. causation. Correlation measures the extent to which 2 variables are related. Causation measures how changes in one variable directly causes changes in the other: falsifiability. Run study multiple times to prove that this is how this natural step works: extraordinary claims. Media over exaggerates everything to get your attention: occam"s razor. If there are 2 explanations, go with the simpler one. Scientific theory: an explanation for a large number of findings in the natural world. You can use the experiment in last week"s lecture powerpoint as a template for your assignment! Population: the entire group that"s of interest to researches.
