- 9. universal and statistical generalizations Universal generalization:Universal generalization: claims that all members of a group have certain attributes or characteristics Asians are good at math. Feminists hate men. Republicans favor tax cuts, Democrats oppose tax cuts.

Generalizations are more likely to hold true if they are confined to specific times, places, or situations Most serial killers are male The majority of journalists are Democrats
- 10. inductive and deductive generalizations Two types of generalizations: inductive and deductive Inductive GeneralizationInductive Generalization:: bases a larger inference on an example, sample, or particular instance example: Babbs bought a Saturn and it runs well. Biff bought a Saturn and it runs well. I guess Saturns are reliable cars. (the generalization is based on a nonrandom sample of 3 cars) example: Of the 19 hijackers on Sept. 11, 15 were Saudis. I think we can safely conclude that Saudi Arabia is a breeding ground for terrorists.
- 11. inductive and deductive generalizations Deductive GeneralizationDeductive Generalization:: proceeds from a general rule or general principle to a specific case example: Brazilians love soccer. Hector is from Brazil, so he probably loves soccer too. example: Don’t give money to that vagrant. They are all winos and drug addicts. example: Biff is a Republican, so of course he’ll be opposed to gun control.
Hinweis der Redaktion
- Birds have feathers.
- The key words change the meaning of the generalization. Some flowers have petals. Flowers always have petals. Flowers never have petals. Most flowers have petals. Many flowers have petals. All flowers have petals. Flowers generally have petals. You have to be VERY careful if you use the word never. Does it NEVER happen?? Is it remotely possible?? Likewise you have to be careful with the words always and all. They include the whole group. Does it ALWAYS happen??
