Document Summary

Simple argument: one inference, from premise to conclusion, draw line before conclusion. Complex argument: more than one inference, at least one intermediate conclusion, use numerical notation to show where inferences occur. Method of difference: looking for something different between two things (e. g. traffic light installed at an intersection) Two distinct groups (common in trials for new drug) Method of concomitant variation: correlation/ association between two events. Statements above are all a single claim, treat them as one argument. Two things have something in common, so they probably have this third thing in common. Method of agreement: looking for something in common between two things (e. g. food poisoning) Some z are not x (needs to be part of z circle, has to be on the line of x circle. ) Equivocation: a feather is light, and anything that is light is not dark. The vast majority think that driving a suv is safer than driving a car.
