If you were trying to decide what kinds of books to buy for the library in your town, how many fifth graders would you interview?
Explain your answer?
It depends on the size of the student's town.
Possible answer: Try to interview at least 100, but more if possible. The larger the sample, the better my data would represent the kinds of books most 5th graders would want to read.
