Mobile App Design Research & Evidence-Based Practice 5

Question 1

Which qualitative data analysis technique involves physically or digitally grouping individual research observations into emergent themes without predefined categories?

Accepted Answer

Affinity diagramming

Answer

Affinity diagramming is a bottom-up technique where individual observations are grouped into clusters that reveal emergent themes rather than fitting data to existing categories.

Question 2

What is the primary ethical obligation a UX researcher must fulfill before a participant engages in any mobile usability study?

Accepted Answer

Obtaining informed consent that clearly explains the study purpose, data use, and right to withdraw

Answer

Informed consent is the foundational ethical requirement — participants must understand what they're agreeing to, how data will be used, and that they can stop at any time.

Question 3

In mobile analytics, what does a high 'bounce rate' on an app's onboarding screen specifically suggest?

Accepted Answer

Users are leaving the onboarding flow immediately without progressing, indicating a friction point at entry

Answer

A high bounce rate on onboarding indicates that a significant proportion of new users disengage at the very first step, pointing to a critical early-experience failure.

Question 4

A researcher conducts tree testing on a mobile app's information architecture. What does a high 'directness' score indicate?

Accepted Answer

Participants navigated to the correct answer without backtracking, suggesting intuitive category labels

Answer

Directness in tree testing measures the percentage of participants who reached the correct location on the first try without backtracking, indicating label clarity and logical structure.

Question 5

When reporting usability test findings, which practice best ensures that severity ratings reflect genuine impact rather than researcher opinion?

Accepted Answer

Using a defined severity scale combining frequency of occurrence and impact on task completion

Answer

A structured severity scale that combines how often an issue occurs with how severely it impairs task completion creates consistent, defensible prioritization independent of individual researcher judgment.
