Document Summary

Hlta10- ch 11: data collection methods in quantitative research. Self-administered questionnaire and interviews methods are most commons mean of data collection. Postal questionnaires/self-administered questionnaire, less of a social encounter than interviews = minimizes social desirability and interviewer bias. > a common method of covering a large, geographically spread pop n quickly and economically than interview methods is to mail respondents a questionnaires to complete @ home w/ a reply-paid envelope for its return. > method is only suitable when issues and questions are straightforward and simple, the pop n is literate and speaks a common language. D: expensive, time-consuming, interviewer bias, despite popularity w/ using this method for health surveys, there has been underreporting of health problems in comparison w/ postal approaches due to social desirability bias. Telephone interview (equal accuracy rates to face to face interviews) A: economic in relation to time (no travelling to interview ppl) and resources.
