Survey response rates are critical to getting as close to the truth about a population as possible. However, organizations struggle with increasing their response rates.
On Tuesday I attended a webinar that suggested Voice Broadcasting (telephone message) that a survey was coming produced a significantly difference response rates than those who did not receive a telephone message. However, I don’t think they compared responses between a Voice Broadcast and just sending an e-mail invitation. I am not sure why they would not compare a Voice Broadcast with an e-mail follow up. However, the researchers did measure how effective e-mail was as a follow up reminder to get people to take surveys.
The results of their experiment suggested that e-mail follow up is more successful with adult volunteers then with girls. My other question or thought would be is how likely would the girl have her own e-mail and that they would have it.
