The primary disadvantage to the use of Internet-based data collection is that
a. It can be difficult to obtain consent.
b. It limits the sample to those who can read and write, use computers, and have Internet access.
c. It can only be used with quantitative research methods.
d. The subject pool tends to be limited.
ANS: B
The main disadvantage of Internet-based data collection has to do with sampling those who are able to read and write, are computer-literate, and who have Internet access. Thus, the poorly educated, elderly, disabled, or disadvantaged may be underrepresented. Researchers who conduct Internet-based research are often able to obtain consent by noting a statement like "Completion and submission of the survey implies consent." Data can be effectively collected for a qualitative study using the Internet. Although there are some sampling limitations in terms of certain populations, the subject pool in general tends to be very large given the extensiveness of the online community not limited by geographic space.
