An advantage of conducting an interview via Skype rather than face-to-face is that:

different modes of communication and their uses information technology communication systems physics

  1. it saves time and money as no travelling is involved.

  2. informants have more time to give detailed, considered responses.

  3. there is no need to transcribe the data

  4. all of the above.

Show answer
Correct Option: D
Explanation:

There are numerous advantages (as well as disadvantages) to conducting an interview online rather than face-to-face. These include practical factors such as the lower cost and greater convenience of conversing electronically, the opportunity it gives respondents to compose careful answers that say exactly what they want to say, and the elimination of transcription error.

Which of the following is a practical problem associated with asynchronous focus groups?

different modes of communication and their uses information technology communication systems physics

  1. It is difficult to send out a welcome message to participants this way.

  2. Moderators cannot be available online 24 hours a day.

  3. Not all participants will have access to the required conferencing software.

  4. Participants do not have enough time to write detailed responses.

Show answer
Correct Option: B
Explanation:

Online focus groups can be conducted either synchronously or asynchronously. In the former case, the researcher can use conferencing software to help participants converse in real time, although this can be problematic if some participants do not have access to the software. (A possible modern remedy for this might be instant messaging services.) Asynchronous focus groups can be conducted via an email distribution list, allowing people more time to compose their responses. However, a problem with this is that the moderator cannot be available online whenever someone is writing a message, and so it can be harder to keep the discussion on track and check the content of messages before they are posted.

Why is it argued that samples recruited online are not representative of the general population

different modes of communication and their uses information technology communication systems physics

  1. Because Internet users are most likely to be young and middle class.

  2. Because women are less likely than men to volunteer for online social research.

  3. Because online researchers only use random probability sampling methods.

  4. None of the below.

Show answer
Correct Option: A
Explanation:

While the Internet can be an extremely useful resource for recruiting research participants, the samples that result are likely to be biased towards certain social groups. This is because Internet users tend to be disproportionately young, middle class, and wealthier and so these characteristics will be over-represented in the sample as compared to the general population.

The two ways of distributing on-line surveys are:

different modes of communication and their uses information technology communication systems physics

  1. Face-to-face or by post

  2. Professionally and quietly

  3. By email and via the World Wide Web

  4. Quantitatively and qualitatively

Show answer
Correct Option: C
Explanation:

Computer-mediated communication provides some great opportunities for distributing a social survey to a relatively large sample of respondents. The researcher can either send their questionnaires out via email, provide a web-link in an e-mail, or they can present the survey on a website, where people are invited to complete it online.

Which of the following is not a problem associated with using websites as sources of data?

different modes of communication and their uses information technology communication systems physics

  1. New websites are constantly appearing while others are disappearing.

  2. It is difficult to find any websites about most topics in business research.

  3. The sample of websites is only as good as the keywords used to search for them.

  4. The 'webspeak' is complex.

Show answer
Correct Option: B
Explanation:

The Internet can be used as a valuable source of quantitative and qualitative data, but there are limitations to this technique of data collection. The researcher's sample of websites will depend on the keywords they used to search for them, and of course websites are prone to being revised, updated and even removed over time. However, there are plenty of websites out there in cyberspace!

Internet is the result of an experiment used to

  1. create a computer network, that would continue to work in the event of a disaster

  2. create a computer network, that can be used to track UFOs

  3. create a computer network, that can be used to save files

  4. create a computer network, that can be used to do scientific computations

Show answer
Correct Option: A

What is the main advantage of an attached email questionnaire over an online social survey?

different modes of communication and their uses information technology communication systems physics

  1. It retains more of the original formatting and so tends to look more attractive.

  2. Recipients will be reassured that the message does not contain a virus.

  3. It requires less expertise for the respondent to open and reply to it.

  4. It is easier to code the answers from this type of questionnaire.

Show answer
Correct Option: A
Explanation:

Online surveys can be sent via email, either embedded in the body of the message or as a separate attachment. The advantage of the latter is that it allows the researcher to use more embellishments and formatting to make the survey look attractive, which in turn may improve the response rate. However, some people may have technical difficulties in opening the attachment, or they may be too worried about computer viruses to risk doing so.
