CIA CIA Card Sorting and Tree Testing Methods 1 — Questions and Answers
Question 1: What is the primary purpose of card sorting in information architecture?
- To test server performance under load
- To discover how users mentally categorize and group information (Correct answer)
- To create visual wireframes of a website
- To measure page load speeds
Correct answer: To discover how users mentally categorize and group information
Card sorting reveals users' mental models by having them group content cards into categories that make sense to them.
Question 2: In an open card sort, participants are asked to:
- Sort cards into predefined categories provided by the researcher
- Create their own category names as they group cards (Correct answer)
- Rank cards from most to least important
- Match cards to existing navigation labels
Correct answer: Create their own category names as they group cards
Open card sorts let participants define their own category names, revealing organic user mental models without researcher bias.
Question 3: A closed card sort is best used when:
- You have no existing information architecture
- You want to discover completely new category structures
- You want to validate whether existing categories work for users (Correct answer)
- You need to test server-side rendering performance
Correct answer: You want to validate whether existing categories work for users
Closed card sorts provide predefined categories and test whether users can correctly place content within an existing structure.
Question 4: Tree testing is specifically designed to evaluate:
- The visual hierarchy of a website's color scheme
- How easily users can find items within a proposed navigation structure (Correct answer)
- The loading speed of hierarchical page trees
- Whether users prefer flat or deep navigation menus
Correct answer: How easily users can find items within a proposed navigation structure
Tree testing measures findability by asking users to locate specific items using only the site's navigation hierarchy, without visual design distractions.
Question 5: What metric is most commonly used to measure success in a tree test task?
- Time on page
- Task completion rate and directness score (Correct answer)
- Bounce rate
- Number of page views per session
Correct answer: Task completion rate and directness score
Tree test success is measured by whether users completed the task and how directly they navigated to the correct item without backtracking.
Question 6: Which card sorting analysis technique groups participants by similarity of their sorting patterns?
- Affinity mapping
- Cluster analysis (Correct answer)
- A/B testing
- Heatmap analysis
Correct answer: Cluster analysis
Cluster analysis in card sorting identifies groups of participants who organized cards similarly, revealing distinct user mental models.
