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.

Question 2

In addition to sample bias and ethical issues (e.g., securing consent, assuring anonymity, and protecting site security), a third concern about factors that may affect the credibility of Internet-mediated study findings is
 
  a. The interviewer's ability to establish rapport with study participants
  b. The fact that use of a pseudonym might cause participants to make up information about the phenomenon
  c. The researcher's ability to transcribe the data gathered through online interviews
  d. Reliability and validity of data, although terms most often applied to quantitative research, might be an issue since the researcher can't verify whether or not participants meet inclusion criteria for the study

Answer to Question 1

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.

Answer to Question 2

ANS: D
Not being able to ensure that participants meet inclusion criteria and being unable to control distractions during data collection are the biggest threats to the validity and reliability of the research findings gathered by Internet-mediated data collection. A skilled and personable interviewer may be able to establish good rapport and to effectively conduct online interviews with study participants. Use of a pseudonym, as well as site controls, helps ensure that participants' identities are not made public. Plans to carefully capture interviews digitally, note-taking, and careful data transcription minimize problems with transcription of data.
