Document Summary
Can be used with most populaion groups (don"t need a phone or funcional literacy) Highest responses rates, also high compleion rates. Can probe and ensure comprehension presence of interviewer reduces number of i don"t know and refusals to respond, can clarify unclear responses. Can control quesion order and who responds (can"t do this with mail in surveys) Interviewers can evaluate poliical knowledge, make observaions about age, racial background, non-verbal informaion. Appropriate for emoionally laden topics there"s an opportunity to build rapport and trust: disadvantages: Survey context should be presented with uniform simulus, but interviewer may not be neutral; hard to control body language, non-verbal cues, sex, age, language or race. Pressure to respond quickly want to ill silence so they respond without thinking, can decrease reliability. Interviewers won"t skip respondents due to remote locaions, dangerous areas, etc. Also avoids issue of people in up-scale neighbourhoods not waning to answer the door.
