Which question-wording is an example of a double barreled question?

A double-barreled question is one that asks about two different issues within a single question, making it difficult for respondents to answer accurately because they may have different opinions about each aspect being addressed.

In this case, the wording "Please rate our customer service on friendliness and efficiency" combines two distinct attributes of customer service: friendliness and efficiency. Respondents may feel positively about one aspect (such as friendliness) while feeling negatively about the other (like efficiency). As a result, it can lead to confusion and may not provide clear insights into customer perceptions.

By addressing these two dimensions in one question, the respondent may struggle to provide a valid response that reflects their views accurately. This results in responses that could inadvertently blend issues that should be evaluated separately, making it a classic example of a double-barreled question. Understanding this concept is crucial for crafting effective survey questions that yield clear and actionable data.

The other options contain inquiries that focus on separate components, allowing respondents to evaluate each aspect independently. For instance, evaluating service and pricing in one question, or asking about expectations versus needs, each presents distinct topics that can be rated or expressed separately, mitigating the ambiguity present in a double-barreled question.
