Text: Inductive Reasoning Examples For each of the following enumerative inductions, (1) identify the target group, sample, and relevant property; (2) indicate whether the argument is strong or weak; and (3) if it's weak, say whether the problem is a sample that's too small, not representative, or both. Assume that the information in the premises of each argument is true. 2. Most people are fed up with celebrities who get on their soapbox and air their political opinions. When people on the street have been asked by TV reporters how they feel about this issue, they almost always say that they wish celebrities would keep their opinions to themselves. Target group: Sample: Relevant property: This argument is strong weak If weak, it's weak because: 3. Doctors used to think that anti-arrhythmic drugs were the cure for irregular heartbeats. They over-prescribed these drugs and fifty thousand patients died. Doctors used to believe that the cure for ulcers was a bland diet, but that turned out to be wrong too. Every new treatment we see these days sounds great, but history tells us that they will all turn out to be worthless. Target group: Sample: Relevant property: This argument is strong weak If weak, it's weak because: 4. I've asked at least a dozen first-year students at this university whether the U.S. should go to war with "terrorist" countries, and they all have said no. So, most of the students at this university are against such a militant policy. Target group: Sample: Relevant property: This argument is strong weak If weak, it's weak because: 5.

Target group: Sample: Relevant property: This argument is strong weak If weak, it's weak because: 6. In every winter for the past twenty years, Buffalo has received several feet of snow. Therefore, Buffalo is likely to get several feet of snow in the next fifty winters. Target group: Sample: Relevant property: This argument is strong weak If weak, it's weak because:
