- Abstract
This article concerns with the detection of interviewer bias in survey data and with eliminating this bias, when found, from the final results. Sample surveys, from the point of view of interviewer bias, have been specifically designed to detect and examine the characteristics of interviewer bias, or they have been designed to secure certain information on a subject of interest. In the latter case, sometimes an attempt is made in the selection of interviewers to minimize the danger of interviewer bias, but little attempt is made to detect interviewer bias in the final survey results and to correct the sample data for this bias. This is the situation encountered in most surveys, and researchers have to face it in analyzing and presenting survey data. In this study interviewer bias was classified into two types--selection bias and answer bias. Interviewer bias was found to depend at least as much upon the questions being asked as on the interviewer. The manner in which each of these biases could be detected and their effect eliminated from the final results was discussed and illustrated with reference to a survey on prefabricated housing. Finally the authors describe a method for finding and correcting that bias.
