BIOL 1110 Lecture Notes - Lecture 5: Null Hypothesis
Document Summary
Name the things that science is not : search for absolutes or absolute truth. Cultural norms of places: correct answers: correct is provisional for same reasons listed above. Depend on the consistency of natural laws. We assume here, that the natural phenomena have a predictability and a consistency that are rooted in natural law. H2o (liquid state): this gonna show the atm is suitable for five chemical reactions to occur. Supernatural events lay outside of science because they subvert natural law* Define methodological naturalism: (a) hyphothesis prosposed by us must involve only natural causes. (b) only way to really do objective science. Hypothetical deductive method: (a) develop hypotheses that attempt to explain observed phenomena. Hypothesis can be derived in a fashion to allow for predictions: for process to push forward you must develop at least two mutually exclusive hypothesis. Null hypothesis: no relationship between variables of intrest. Control: test subject live in a normal environment.
