What should a questionnaire's layout prioritize to promote user-friendliness?

A questionnaire's layout should prioritize clear text and font size to promote user-friendliness because clarity directly impacts how easily respondents can read and understand the questions. If the text is legible, with an appropriate font size, respondents are more likely to engage with the questionnaire effectively, reducing the chances of confusion or frustration. This approach enhances the overall experience for participants, ensuring they can concentrate on providing accurate and thoughtful responses.

In addition, clear formatting, which includes proper spacing and organization of questions, further contributes to the ease of navigation through the questionnaire, leading to more reliable data collection. Prioritizing user-friendliness in the layout ultimately helps in obtaining high-quality responses, as participants feel more comfortable completing the survey.
