You can post a survey or participate in a survey on just about any topic you can think of. The only problem is what to do with all of this information. It appears that most of the surveys on-line are entertainment oriented. The academic and research oriented surveys, however, present a problem. The academic and research surveys need to begin addressing issues of external validity .
Few surveys comment about the fact that they are drawing a nonrandom and nonrepresentative sample.
First, the samples are nonrandom because people are self-selecting to participate in these surveys. Usually, the participants are most interested in your topic, hence they take the time to answer your survey. Second, the sample of people that on-line surveys draw from are not representative of the population. The growth of this digital world has brought about concerns of World Wide Web and Internet surveys. The proliferation of advertisements on the Net requires new and improved ways of assessing audience desires, beliefs, and opinions.
