Misleading claims with numbers

There are a few different ways of having a misleading claim with numbers. One of these is called comparing apples and oranges. this is when someone compares a number of one item with a number of another item that has nothing to do with the first item. For example, I have two cats and my brother has 5 dogs. Who has more? This is too vague of a comparison because it does not say who has more of what? This makes this comparison completely meaningless. Another misleading claim with numbers is often used in advertisements in commercials or magazines. For example, on Pro Active commercials, they will say that 90 percent of people who use this product see results or get clear skin immediately. But this is a mistaken comparison. I do not know how many people they used in their comparison. If it was 90 out of 100 then I would most likely use the product and purchase it. But it is it 9 out of 10 people, it is not so appealing and might not think its worth my money.

Signs of Reasoning

Signs of reasoning comes in different forms depending on the context given. Some of these are logic which has forms of inductive and deductive reasoning, which points out the facts. It is either true or not true. Another form is scientific reasoning. This is based on experiments, observations, and predictions. While testing scientific  reasoning it is important to look at the consistency acceptability, and reatability. Visual/aural proof which is uaually done in digital media and gives visual proof which has the most credibility and is growing to be a very useful source of reasoning. Enthymemes is a form of reasoning based on assumption of what the audience hears. Storytelling is a common cultural from of reasoning. It gains the audiences attention and gives examples and causes and effect in their storys.

Reasonings.

  • Reasoning by analogy: Education is like a safety blanket.Safety blankets keep you safe and education can help you feel safe in getting a good career in the future. Reasoning by analogy is a comparison. It may be reasonable but it is not an argument.
  • Sign reasoning: I walk to school because I missed the bus. The only way I could get to school was walking. This is logical reasoning.
  • Casual reasoning: Working out makes you skinny. This is a casual reasoning because it hold a cause and effect. This statement is generalized and isn't always true. It's just assumed
  • Criteria reasoning: My friend thinks all black cats are bad luck. So when she see's a black cat I assume she is goin to freak out.
  • Reasoning by example: You need to study before taking a test. One time I took a test and thought I'd do okay since I went to class everyday. I got a D because I did not study and couldn't remember some of the stuff we went over in lecture.
  • Inductive reasoning: I always check my locks before I leave. So when I go to my friends house I will check my lock.
  • Deductive reasoning: All cats meow. My cat meows. This in deductive because both statements are true..
