User Experience Design User Experience Design Usability Testing & Evaluation 2 — Questions and Answers
Question 1: What is a heuristic evaluation in UX?
- An automated performance test
- An expert review of an interface against established usability principles (Correct answer)
- A user survey about visual preferences
- A technique for mapping user journeys
Correct answer: An expert review of an interface against established usability principles
A heuristic evaluation is an expert-based method where evaluators inspect a UI against recognized usability heuristics to identify potential issues.
Question 2: What is a 'remote unmoderated usability test'?
- A test where participants complete tasks on their own devices without a live facilitator (Correct answer)
- A test conducted by a team member not on the core UX team
- A test that measures emotional response without observation
- A test held in a different time zone
Correct answer: A test where participants complete tasks on their own devices without a live facilitator
Remote unmoderated tests allow participants to complete tasks independently on their own devices at their own time, recorded by a software platform for later review.
Question 3: In UX evaluation, what is 'error rate'?
- The frequency with which users make mistakes during task completion (Correct answer)
- The number of broken links on a page
- A measure of server downtime
- How often the design fails accessibility audits
Correct answer: The frequency with which users make mistakes during task completion
Error rate measures how often users make mistakes or take incorrect actions when attempting to complete a task, indicating areas of design confusion.
Question 4: What is 'cognitive walkthrough' as a UX evaluation method?
- Having users memorize interface layouts
- Evaluators simulate a user's thought process step by step through a task (Correct answer)
- A walkthrough video recorded for training purposes
- A technique for documenting user flows
Correct answer: Evaluators simulate a user's thought process step by step through a task
Cognitive walkthrough is a structured usability inspection method where evaluators step through tasks from a user's perspective to identify learnability issues.
Question 5: What is the purpose of an A/B test in UX?
- To compare two versions of a design to determine which performs better (Correct answer)
- To test a product with two different user groups
- To test accessibility against two different screen readers
- To compare desktop vs. mobile layouts
Correct answer: To compare two versions of a design to determine which performs better
A/B testing presents two design variants to different user groups simultaneously and uses performance data to determine which version better achieves the desired goal.
Question 6: Which metric measures how much effort users expend to interact with a product?
- Net Promoter Score (NPS)
- Customer Effort Score (CES) (Correct answer)
- Task completion rate
- System Usability Scale (SUS)
Correct answer: Customer Effort Score (CES)
Customer Effort Score measures how easy or difficult users find it to interact with a product, with lower effort correlating to higher user satisfaction.
