Generalizations

The Epstein text describes sever kinds of generalizations as well as what makes a good generalization versus a bad one. I chose to look further into the various kinds of samples. The three main kinds of smapling the author examines are Representative Sampling, Random Sampling and Haphazard sampling. Representative Sampling is a sampling that accurately represents the population of the subgroup within proportion of the entire population. Random sampling is when a sample is chosen at complete random, like when names are chosen from a fishbowl. Haphazard sampling is when the sample is chosen with an intentional bias. Haphazard sampling can be representative but there is no good reason to believe it is representative because those chosen for the sample were selected for a specific reason. The book also explains that representative samplings are ones that are not intentionally biased.
