Something I found Interesting and Useful

Something in chapter 14 that I found useful and interesting is Generalizing. We as people generalize things everyday. Epstein says that generalizing is how we make sense of our world. He also states how poll takers and scientists generalize also not just us. Generalizing: We are generalizing if we conclude a claim about a group, the population, from a claim about some part of it, the sample. To generalize is to make an argument.
Sometimes the general claim that is the conclusion is called the generalization; sometimes we use that word for the whole argument. Plausible premises about the sample are called the inductive evidence for the generalization. It also says that to evaluate whether a generalization is good, we need to see it as an argument. Something that was also useful was statistical generalization. That means that sometimes the generalization we want and we're entitled to isn't "all" but "most" or 72%: The same portion of the whole as in the sample will have the property.
