Maria is worried about the representativeness of her study. she is conducting interviews, but each one seems to last at least five hours. given that she only has one month to collect her data, what strategy might she use to increase her sample size?
It seems as though Maria needs to interview more people to get the best representatives for her study. a good strategy would be to screen representatives first by giving them a written test to see if they would even be close to what she was looking for then from those written tests she could choose who to interview and the interview could be shorter because a lot of information she would have discovered by the written test.
