Quizplus · Accepted Answer

All of the above options represent problems for reliability. A single observer may introduce bias or errors in their observations, using different interviewers may lead to variations in how questions are asked or interpreted, and having different coders may lead to discrepancies in how data is evaluated and categorized. Therefore, all three options pose potential threats to the reliability of research findings.
