Document Summary
Pros: large samples are feasible, good for describing a large population, flexible, allows development of operational definitions from observations. Cons: standardization, can be inflexible, possible social desirability taking place. Response rate: # ppl taking part divided by # selected to participate (but in percent) Cooperation rates: proportion of interviewed cases ever contacted. ** should test for nonresponse bias when possible. Advantages: have higher response rates, completion rates are higher, less chance of interviewer being rejected if seen in-person. Interviewer should be a neutral medium who doesn"t exercise any bias. Interviewer should be familiar with the questionnaire: follow exact wording, record exact responses, probe for elaboration if the answer is incomplete. Pros: money, time, greater control over data collection. Cons: bogus, ease of hanging up, answering machines/voice mail. Data collected & processed by one person is reanalyzed for another person (sometimes for different purpose) Is cheaper & faster than performing original surveys.
