Suppose you want to know how many books in a bookstore have only male authors, only female authors, or both male and female authors (the “bookstore” in this case might be a large retail store, the textbook section of your college bookstore, or all the books in the stacks of your library). Because there are thousands of books in the store, you decide to study a sample of the books rather than examine every book there. Describe a possible sampling procedure using a nonprobability sampling technique. Then describe how you might sample books using a probability sampling technique. Now speculate on the ways that the outcomes of your research might differ using the two techniques.
