UX Usability Testing 1 — Questions and Answers
Question 1: What is the primary goal of moderated usability testing?
- To benchmark a competitor's product
- To observe how real users interact with a product while guiding them (Correct answer)
- To automate user feedback collection
- To measure server response times
Correct answer: To observe how real users interact with a product while guiding them
Moderated usability testing involves a researcher observing and sometimes prompting participants to reveal usability issues in real time.
Question 2: What distinguishes unmoderated usability testing from moderated testing?
- Unmoderated testing uses eye-tracking only
- Participants complete tasks independently without a researcher present (Correct answer)
- Unmoderated testing requires a lab environment
- Unmoderated testing only measures task success rate
Correct answer: Participants complete tasks independently without a researcher present
In unmoderated testing, participants complete assigned tasks on their own, often using a tool like UserZoom, which records behavior automatically.
Question 3: What is a 'task scenario' in a usability test?
- A description of the product's technical architecture
- A realistic narrative that gives participants context for completing a task (Correct answer)
- A list of all features to be tested
- A script the participant reads aloud
Correct answer: A realistic narrative that gives participants context for completing a task
A task scenario frames a task in a realistic context, making it easier for participants to understand what they should try to accomplish.
Question 4: Which metric measures the percentage of participants who successfully complete a given task?
- Net Promoter Score
- Task completion rate (Correct answer)
- System Usability Scale
- Error frequency
Correct answer: Task completion rate
Task completion rate is a binary or partial-credit metric that shows what proportion of participants accomplished the intended goal.
Question 5: What does 'time on task' measure in a usability test?
- How long the researcher observed a session
- How long a participant takes to complete a specific task (Correct answer)
- The total duration of the usability study
- The time between task assignment and participant recruitment
Correct answer: How long a participant takes to complete a specific task
Time on task is an efficiency metric that records how long users need to complete a task, with shorter times generally indicating better usability.
Question 6: Why is the System Usability Scale (SUS) widely used in usability testing?
- It measures server uptime
- It is a validated, quick 10-item questionnaire that produces a single usability score (Correct answer)
- It replaces the need for task scenarios
- It is required by US federal accessibility law
Correct answer: It is a validated, quick 10-item questionnaire that produces a single usability score
SUS provides a reliable, technology-agnostic usability score that can be benchmarked across products and industries with just 10 questions.
