Expert writing Tips

Best practice

When describing the completion of a questionnaire, consider the specific context. If you want to emphasize the act of answering questions, use "answered the questionnaire". If you want to highlight the submission of the form, use "submitted the questionnaire".

Common error

Instead of saying "the questionnaire was completed by the participants", use the active voice: "the participants completed the questionnaire". This makes the sentence more direct and easier to understand.
