User Experience Design User Experience Design 5 — Questions and Answers
Question 1: What is the main risk of conducting usability tests exclusively with convenience samples such as colleagues or friends?
- Tests will take longer to complete
- Participants may not represent the actual target users, reducing validity (Correct answer)
- Participants will be too critical of the design
- The number of sessions will be insufficient for statistical significance
Correct answer: Participants may not represent the actual target users, reducing validity
Convenience samples often lack the characteristics, behaviors, and pain points of real target users, which can lead to misleading findings.
Question 2: Which of the following best describes 'interaction cost' in UX?
- The financial budget allocated for user testing
- The sum of physical and mental effort required to achieve a user's goal (Correct answer)
- The number of screens in a user flow
- The time a developer spends implementing a design
Correct answer: The sum of physical and mental effort required to achieve a user's goal
Interaction cost encompasses all the physical actions (clicks, scrolls, typing) and mental effort (reading, deciding, remembering) a user must expend to accomplish a goal.
Question 3: When designing for touch interfaces, what does 'thumb zone' analysis help a designer determine?
- The optimal font size for mobile screens
- Which areas of the screen are most comfortably reachable with a thumb during one-handed use (Correct answer)
- How much vertical scrolling is acceptable on a mobile page
- The minimum tap target size required by accessibility guidelines
Correct answer: Which areas of the screen are most comfortably reachable with a thumb during one-handed use
Thumb zone analysis maps areas of a mobile screen into easy, hard, and reachy zones based on natural thumb movement during one-handed use.
Question 4: What does it mean when a UX design is described as 'inclusive'?
- It works only on the most popular devices and browsers
- It is designed to be usable by people with a wide range of abilities, contexts, and backgrounds (Correct answer)
- It includes all possible features to satisfy every user
- It is accessible only to users with disabilities
Correct answer: It is designed to be usable by people with a wide range of abilities, contexts, and backgrounds
Inclusive design aims to create products usable by the broadest possible range of people, considering diverse abilities, languages, cultures, and situational constraints.
Question 5: A product team wants to validate a hypothesis about a new feature before investing in full development. The fastest approach is to build a:
- High-fidelity prototype with full interactions
- Minimum viable prototype (MVP) or even a paper prototype (Correct answer)
- Complete beta version for a limited audience
- Functional prototype with real backend data
Correct answer: Minimum viable prototype (MVP) or even a paper prototype
A minimum viable prototype—even a paper or low-fidelity version—lets teams test core assumptions quickly at minimal cost before committing to development.
Question 6: In UX writing, what does 'microcopy' refer to?
- Short marketing taglines on landing pages
- Small but critical pieces of UI text such as button labels, error messages, and form hints (Correct answer)
- The legal disclaimers found at the bottom of a page
- Text displayed in tooltip overlays during onboarding
Correct answer: Small but critical pieces of UI text such as button labels, error messages, and form hints
Microcopy is the small functional text throughout an interface—labels, placeholders, error messages, confirmation prompts—that guides users through interactions.
Question 7: The concept of 'satisficing' in user behavior, coined by Herbert Simon, means that users tend to:
- Spend significant time finding the perfect solution
- Choose the first option that is 'good enough' rather than the optimal one (Correct answer)
- Become frustrated and abandon tasks when options are limited
- Prefer interfaces with the most features available
Correct answer: Choose the first option that is 'good enough' rather than the optimal one
Satisficing combines 'satisfy' and 'suffice' — users stop searching once they find an option that meets their minimum threshold, not necessarily the best one.
