Gi Woong Yun & Craig W. Trumbo (2000).Comparative Response to a Survey Executed by Post, E-mail, & Web Form. Journal of Computer-Mediated Communication, vol.6 (1):
"Recent developments in communication technologies have created alternative survey methods through e-mail and Web sites. Both methods use electronic text communication, require fewer resources, and provide faster responses than traditional paper and pencil methods. However, new survey methodologies also generate problems involving sampling, response consistency and participant motivation. Empirical studies need to be done to address these issues as researchers implement electronic survey methods."
