Gathers information in a relatively short time: understand the advantages and disadvantages of using interviews versus questionnaires in survey research. Allow researcher to develop a close relationship/sense of trust with subject more open and honest responding. Difficult for interviewers to be trained to ask questions in an unbiased manner. More honest responses because it feels more anonymous. Question order (may not answer questions in the order they are written) surveys: understand how probability sampling is used to ensure that a sample is representative of the population. Simple random sampling: ensure that each person in the population has an equal chance of being selected to be in the sample. Use a random number generator and correlate that to the list of people in the population.
