In a survey which uses lay interviewers to interview one person about his or her health and the health of household members, the
sources of error include:A. the person with disease has had no symptoms and is not aware of the disease.B. the respondent provides the information but the interviewer doesn't record it or records it incorrectly.C. the interviewer doesn't ask the questions that he or she is instructed to ask, or asks them incorrectly.D. the person has had symptoms and has had medical attention but does not know the name of the disease.E. all of the above
There are multiple sources of error, considering all of the options mentioned in the question as sources of error make the survey more complete because it is considering a wide range of situations where the person or the interviewer can make a mistake, which is useful for analysis of the results and to know where the system should be improved.
