What is a primary characteristic of high reliability in questionnaires?

• A. Use of open-ended questions
• B. Involvement of the interviewer
• C. Large sample size and standardised format
• D. Subjective interpretation of responses

Answer: (C)

A primary characteristic of high reliability in questionnaires is the use of a large sample size and a standardized format. This approach ensures that the data collected is consistent across different respondents, which is essential for reliability. A standardized format minimizes variability in how questions are understood and answered, allowing for more precise comparisons and repeatability of results. When a questionnaire is administered to a large sample, it enhances the statistical power of the findings and reduces the impact of outliers or idiosyncratic responses, contributing to the overall reliability. This combination of standardization and sufficient sample size helps to ensure that the findings are stable and can be reproduced in future studies, which is a key aspect of reliable research instruments in sociology.
