What does "Question Randomization" achieve in a survey?

Question randomization is a powerful technique used in survey design to enhance the quality of data collected. When questions are presented to respondents in a different order for each participant, it helps to mitigate potential bias that could arise from the order in which questions are answered. If the same set of questions is presented in a consistent order, earlier questions may influence how respondents perceive or respond to later questions. By randomizing the order, each respondent has an equal chance of answering questions in any sequence, which helps ensure that responses are more reflective of their opinions rather than how the questions are stacked against each other.

This approach increases the reliability of the data collected, leading to more valid insights. It’s particularly useful in cases where questions might lead the respondent to think of certain aspects in a specific light, thus altering their responses to subsequent questions. Therefore, the correct choice highlights the importance of randomization in achieving unbiased survey results.
