Which of the following is identified as a weakness in the practical?

• A. The sample size was too large
• B. Use of a diverse sampling method
• C. Short questionnaire with not enough questions
• D. Long and complicated procedures

Answer: (C)

The identification of a short questionnaire with not enough questions as a weakness highlights a significant concern in research methodology. When a questionnaire lacks sufficient questions, it may not comprehensively cover the constructs it aims to measure. This can lead to superficial insights, as the data collected may not fully reflect the complexity of the phenomenon being studied.

In psychological research, it's essential to capture diverse aspects of a participant's experience or behavior. A brief questionnaire might limit the depth of responses and fail to account for various factors influencing the subject matter. Consequently, the reliability and validity of the findings may be compromised, as the instrument may not be able to detect subtle effects or differences within the population under study. A well-structured questionnaire typically balances brevity with the need to gather enough information to draw meaningful conclusions.
