Chapter 14: Interesting Concept


In chapter fourteen it was based on generalizing.  The one thing I found interesting in the chapter that was also helpful was the “three premises needed for a good generalization”.   In order for an argument to be a generalization it needs to have three premises.  The first one listed is “the sample is representative”.  The sample needs to be representative if “no one subgroup of the whole population is represented more than its proportion in the population.”  Secondly, “the sample is big enough”, you need to measure how much more likely your generalization is going to be “accurate as you increase the number in your sample”. Lastly, “the sample is studied well” we need to ask questions that are not bias, in order for it to be investigated well.  All three premises are needed in order for it to be considered a good generalization.  Without the three premises your generalization will be considered bias.
