Which method is considered a best practice for informing respondents about the protection of their answers in an online survey?

The informed consent process plays a crucial role in ethical research, particularly in online surveys. Using it to explain aspects like data transmission and the absence of IP recording provides transparent information to respondents about how their data will be handled. It reassures them that their identity will not be tracked through their IP address, which can enhance participants' trust and willingness to provide honest and thoughtful responses.

This method aligns with best practices in ethical research by prioritizing transparency and participant understanding. By clearly detailing the data protection measures, including the absence of IP recording, respondents are more likely to feel secure about their participation, which can lead to higher response rates and more reliable data. This approach respects respondents' rights to know how their information is managed, promoting ethical standards in research.
