MRA Data Collection & Sampling 4

Question 1

A researcher uses geofencing technology to send a mobile survey to shoppers who enter a retail store. This is best classified as:

Accepted Answer

Location-triggered intercept survey

Answer

Location-triggered intercept surveys use geofencing to automatically invite participants to a survey when they enter a predefined geographic area.

Question 2

What is the main advantage of using a 'split-ballot' design in questionnaire research?

Accepted Answer

It allows testing of different question wordings or formats on separate subsamples

Answer

Split-ballot designs expose different versions of a question (wording, scale, or order) to separate random subsamples, enabling researchers to measure the effect of those differences.

Question 3

In the context of online survey research, what is 'speeders' and why are they a data quality concern?

Accepted Answer

Respondents who complete surveys far below the median completion time, suggesting they did not read questions carefully

Answer

Speeders complete surveys in unrealistically short times, indicating they likely skipped reading questions and provided low-quality, random, or inattentive responses.

Question 4

Which sampling method is most vulnerable to the 'volunteer bias' problem?

Accepted Answer

Self-selection (opt-in) sampling

Answer

Self-selection sampling allows individuals to decide whether to participate, meaning those who volunteer may differ systematically from non-volunteers, introducing volunteer bias.

Question 5

A researcher wants to study how consumers naturally interact with a new product in their home environment without researcher interference. The most appropriate data collection method is:

Accepted Answer

In-home ethnographic observation or diary study

Answer

In-home ethnographic observation or diary studies capture natural behavior in the actual usage environment without the artificial conditions of a lab or survey.
