Document Summary
Experiment= a systematic research study in which the investigator directly varies one factor while holding others constant and observes results of variation. Method of agreement states that if x is regularly followed by y the x is sufficient for y to occur and could be a cause of y- this is if x then y . Method of difference states that if y does not occur when x does not occur then x is necessary for y to occur, if not x then not y . Method of agreement/difference provides conditions for the production of y. Only can come to conclusions with a certain amount of confidence. Independent variable is the factor of interest to the experimenter. Sometimes called manipulated factor /variable cause researcher has fully control over it. All miv have two levels, aka a comparison between two situations. Independent variables fall into three categories: situational, task and instructional variables.
