The correct option is b.
Susan meets the necessary requirements for inclusion in a survey. yet, she is not included in the survey because of Rating cards.
Excluding someone from a survey sample when they meet the necessary requirements could happen due to various mechanisms or errors in the survey process. Let's break down each of the options and how they might be involved:
A. Supervisor instructions:
This could occur if Susan's inclusion or exclusion was based on specific instructions from a supervisor overseeing the survey. The supervisor might have directed the interviewer to exclude Susan for some specific reason.
B. Rating cards:
Rating cards typically contain information about potential survey participants, including their suitability for the survey. If Susan's rating card indicated that she should be excluded for some reason, the interviewer might have followed this guidance.
C. Quotas:
Quotas are predefined targets for specific demographic groups within a survey sample. If Susan belonged to a group that had already met its quota, she might have been excluded to maintain balance within the sample.
D. Interviewer instructions:
Interviewers may receive instructions about which individuals to include or exclude based on specific criteria. If Susan's exclusion was due to such instructions, it would fall under this mechanism.
E. Call record sheet:
Call record sheets typically contain information about attempted and completed survey calls. If Susan's call record sheet indicated that she was not contacted or interviewed for some reason, this could be the mechanism behind her exclusion.
The answer is Rating cards.
