The use of the internet as a research tool for data collection has increased substantially in the past decade. Online surveys have the potential to facilitate researchers in several ways, including subject recruitment, data collection, data tabulation, and data analysis. However, careful considerations must be taken when designing online surveys to ensure their validity and representativeness. To help researchers in this process, the current paper has three primary objectives: (1) To discuss the methodological issues involved in conducting online surveys (e.g., accessing populations, and controlling testing conditions); (2) To discuss the statistical considerations involved in using large samples for hypothesis testing (e.g., p-values vs. effect sizes); and (3) To review the literature on the use of internet-based surveys. The paper discusses these issues, using several internet surveys that the authors have conducted at one of the universities in the Midwest in the United States, and some examples of university surveys available through Wold Web Sites.
