Document Summary
In empirical reasoning, arguments try to establish facts about the world. It is characterized by probable, not certain, reasoning. A generalization is the process of moving from specific observations about some x within a group to general claims about all the x members of the group. Generalizations are based on an incomplete survey of the evidence. When we generalize we assume that present or future occurrences will resemble the past. P2: proportion 1 of x"s in s are y. P1: 10 students in modr 1730 are surveyed to represent 50 in total. P2: 8 out of 10 students have perfect attendance. Generalizations can result in several different types of claims. 2. 5% of the microchips fail to meet our specifications. If a sample size is too small to represent a group, then the generalization derived is likely to innacurate. A sample size needs to be large enough to represent the demographics of the group for which it is deriving a conclusion.
