For my last and final post for this class, I found random sampling from chapter 14 interesting. Random sampling is used in a lot of research however I did not know it can be used for critical thinking. According to Epstein, random sampling is, "a sample is chosen randomly if at every choice there is an equal chance for any one of the remaining members of the population to be picked." It is obvious that surveying every individual in the world is impossible, therefore using random sampling is the best option because any person can be picked. Selecting random people to conduct an experiment is not as easy as it seems. In the book it says that mathematicians prepare random numbers for the selection. Random sampling gives people a good reason to believe it is good sampling because it is not biased. An argument would be valid because its premises are not false due to the sample selection.
