What is the advantage of using Internet surveys to supplement traditional postal questionnaires?

  1. Postal questionnaires generally produce a higher response rate.

D Correct answer
Explanation

There is a growing tendency for researchers to administer questionnaires through more than one medium. Thus they might send out a printed copy of the questionnaire by post to everyone in the sample, but explain in the covering letter that the survey can also be found online, for example at a web site. This allows recipients of the letter to choose whether to respond by post or online, and so it has the potential to improve the study's response rate. Meanwhile, there is growing evidence that using online questionnaires alone produces a lower response rate than postal surveys. It seems that Internet users have become quite sophisticated in their attitudes to unsolicited emails. Spam filters and security software may inadvertently trash some messages, particularly those with attachments.

The setup costs in establishing 

  1. the LAN is more than in WAN

  2. the WAN is more than in LAN

  3. LAN and WAN are same

  4. None of the above

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In LAN, If there is a need to set-up a couple of extra devices on the network, it is not very expensive to do that and hence cost associated to setup a LAN is less

For WANs since networks in remote areas have to be connected the set-up costs are higher.
