LIFESCI 2A03 Lecture Notes - Lecture 3: Syllogism, Deductive Reasoning, Alternative Hypothesis
Document Summary
Reject hypothesis supporting experimental evidence = strengthen hypothesis but will never know for certain that hypothesis is true. Fail to reject hypothesis e. g. : just because you"ve only seen white swans, it does not prove that all swans are white. but the observation of a single black swan can falsify that statement. So easier to prove something isn"t what it is (or doesn"t exist) than to prove that something is what it is. Alternative hypothesis (ha) all other hypothesis that is not the null hypothesis hypothesis contrary to null hypothesis usually the research hypothesis. False negative bc the negative result is false, also, duh. innocent until proven guilty = no difference/hypothesis wrong until proven there"s a difference/hypothesis is right. Set of experimental units included in the study. The rules + procedures by which the treatments are assigned to the experimental units. Measurements that are made on the experimental units after the treatments have been applied.
