Response rates of online surveys in published research: A meta-analysis

The response rates of online surveys were often examined in the literature by comparing to other modes of surveys. Questions regarding what constitutes a respectable response rate for online surveys in research remained unanswered. To fill in the knowledge gap, we conducted a comprehensive search, screened 8672 studies, and examined 1071 online survey response rates reported in education-related research. Our analyses showed the number of online surveys in published research grew steadily across the years. The average online survey response rate is 44.1%. Our results indicate that sending an online survey to more participants did not generate a higher response rate. Instead, sending surveys to a clearly defined and refined population positively impacts the online survey response rate. In addition, pre-contacting potential participants, using other types of surveys in conjunction with online surveys, and using phone calls to remind participants about the online survey could also yield a higher response rate. The use of incentives did not show a significant impact on the response rate of online surveys. Other factors that impacted the rates included the funding status of a project, and the age and occupation of the participants. Concrete suggestions for reviewing and improving the online survey response rates are provided.
