Guidelines for developing a robust web survey.

A web based survey is an effective tool which is used frequently in academic and non academic researches. Increase in the internet usage and easy access to web technology facilitate the growing popularity of web surveys but absence of exhaustive literature on web surveys presents a significant challenge. This paper presents basic guidelines for developing a robust web survey. Aspects related to data quality, coverage bias, questionnaire design, non response bias, response bias, processing error, data duplication and pilot testing are discussed in detail. The paper closes with suggestions on key areas in which advance research is required to enhance the data quality of web questionnaires.
