Drupal Research & Evidence-Based Practice 3 — Questions and Answers
Question 1: What does a statistically significant result mean in the context of Drupal UX research?
- The result was visually impressive in the interface
- There is a low probability that the observed difference occurred by chance (Correct answer)
- The test ran for more than one week
- At least 10 users participated in the study
Correct answer: There is a low probability that the observed difference occurred by chance
Statistical significance (typically p < 0.05) means the probability that results occurred randomly is below an accepted threshold, justifying evidence-based decisions.
Question 2: In Drupal, which module family is best suited for implementing multivariate testing scenarios on landing pages?
- Devel
- AB Test or similar experimentation modules (Correct answer)
- Backup and Migrate
- Token
Correct answer: AB Test or similar experimentation modules
Dedicated A/B or multivariate testing modules allow Drupal sites to serve different content variants and track conversion differences systematically.
Question 3: When researching accessibility compliance on a Drupal site, which standard should guide evidence-based remediation?
- OWASP Top 10
- WCAG 2.1 AA (Correct answer)
- ISO 27001
- PCI-DSS
Correct answer: WCAG 2.1 AA
WCAG 2.1 AA is the internationally recognized accessibility standard and the benchmark used by Drupal's own accessibility team.
Question 4: Which Drupal tool helps developers collect performance benchmarks to make evidence-based caching decisions?
- Devel module's query log and XHProf integration (Correct answer)
- Webform analytics dashboard
- Taxonomy term reports
- Media library statistics
Correct answer: Devel module's query log and XHProf integration
Devel combined with XHProf provides per-request query counts and timing data, giving measurable evidence for where caching improvements matter most.
Question 5: What is the recommended evidence-based approach before removing a Drupal contributed module from a production site?
- Delete the module files and clear cache
- Audit dependent modules, run tests, deploy to staging, verify functionality, then remove from production (Correct answer)
- Disable the module directly on production without testing
- Replace it with a custom module without testing the replacement
Correct answer: Audit dependent modules, run tests, deploy to staging, verify functionality, then remove from production
Removing modules without a staged, tested process risks breaking dependent functionality; a methodical audit and staging test provides evidence that removal is safe.
Question 6: Which Drupal feature supports content audit workflows needed for evidence-based content strategy?
- Views with exposed filters on content types, status, and dates (Correct answer)
- The core Contact module
- CKEditor spell checker
- Drupal's Aggregator module
Correct answer: Views with exposed filters on content types, status, and dates
Views with exposed filters lets content strategists audit all nodes by type, publication status, author, and date—providing the data needed for evidence-based content decisions.
Question 7: When evaluating SEO performance on a Drupal site, which module provides the most direct evidence through structured data output?
- Pathauto
- Schema.org Blueprints (Correct answer)
- Redirect
- Simple XML Sitemap
Correct answer: Schema.org Blueprints
The Schema.org Blueprints module generates validated structured data markup that search engines use, providing measurable evidence of semantic richness for SEO audits.
