User Testing Exam Participant Recruitment and Screening 2

Question 1

What is 'snowball sampling' in user research?

Accepted Answer

Existing participants refer new participants who share similar characteristics

Answer

Snowball sampling leverages existing participants to refer others from their network, useful for reaching niche or hard-to-find populations.

Question 2

What does 'theoretical saturation' mean in qualitative user research?

Accepted Answer

The point at which additional participants yield no new significant insights

Answer

Theoretical saturation occurs when recruiting more participants no longer reveals new themes or insights, indicating sufficient data has been collected.

Question 3

Why is a no-show rate important to account for in participant scheduling?

Accepted Answer

Because some recruited participants will cancel or not attend, requiring overbooking to meet target sample size

Answer

Accounting for the no-show rate (typically 10–20%) by over-recruiting ensures you still reach your target sample size despite cancellations.

Question 4

What is the main advantage of recruiting from a professional panel or research recruitment agency in the US?

Accepted Answer

Faster access to pre-screened participants matching specific demographic criteria

Answer

Professional panels and agencies maintain large databases of pre-screened participants and can quickly match candidates to specific study criteria.

Question 5

When recruiting for a mobile app usability test, what device-related screening criterion is most important?

Accepted Answer

Participants must own and regularly use the type of mobile device the app targets

Answer

Ensuring participants own and regularly use the target device type guarantees realistic usage context and relevant mental models.
