2. Which of the following is NOT a reason for doing a pilot study?
Spot errors and ambiguity in wording.
Spot errors in the interface design and the protocol
Find out how long it takes to complete the survey
Increase the sample size by including data collected from the pilot study

3. Completeness Efficiency Insight None of the above

“3” is universally accepted as the middle position and thus the data are accurate.

5. Which of the following is NOT an advantage of online survey?
Lower error rate
More freedom (e.g. skip logic)
Randomize item order to counter the testing effect
Higher completion rate

6. Which of the following statement(s) is/are true?
Survey data are not very accurate because people do not tell you the truth all the time.
Behavioral data are collected in experimental setting.
Researchers cannot use Web-based data collected by Google, YouTube, and Facebook due to ethical concerns (e.g. privacy).
