Quizplus · Accepted Answer

Mail and online surveys tend to have the lowest response rates compared to telephone and face-to-face surveys. This is because people may be more likely to ignore or delete emails or physical mail, and online surveys may be perceived as spam or untrustworthy. Additionally, these methods may require more effort or time from participants compared to answering a phone call or having a conversation in person.
