Open ended questions generally serve a specific purpose:
- What products/brand/advertisements do you recall?
- You said X, why did you say that?
- Would you purchase/recommend X? Why/why not?
These open-ended questions generate a wider spectrum of codes than the usual standard close-ended questions, especially when the codeframe is kept to a small list, a key aspect in any mobile first survey. However, open-ended questions can also produce less impactful data (sometimes termed as gibberish data) when stock standard question wording is used, as illustrated above. The key to making an open ended question valuable is to frame the question wording to be thought-provoking, making it meaningful for the respondents and making them want to share their views fully, in an environment where this is easy to do.
