Research Methods
This section provides practical guidance on various UX research methodologies. Each method includes when to use it, how to conduct it, and templates to get started.
Choosing the Right Method
Select your research method based on:
Research questions - What do you need to learn?
Project stage - Discovery, validation, or optimization?
Resources available - Time, budget, and access to users
Type of insights needed - Qualitative depth vs. quantitative scale
Research Methods by Type
Common Methods
User Interviews
When to use: Early discovery, understanding user needs and contexts
Participants: 5-8 users per segment
Duration: 45-60 minutes per session
Output: Themes, pain points, opportunity areas
View detailed guide →
Usability Testing
When to use: Evaluate interface designs, test task flows
Participants: 5-8 users (sufficient to find 85% of issues)
Duration: 30-60 minutes per session
Output: Usability issues, success metrics, recommendations
View detailed guide →
Surveys
When to use: Validate findings at scale, measure satisfaction
Participants: 100+ for statistical significance
Duration: 5-10 minutes per response
Output: Quantitative data, trends, statistical validation
View detailed guide →
Card Sorting
When to use: Organize information architecture, validate navigation
Participants: 15-30 users
Duration: 20-30 minutes per session
Output: Mental models, grouping patterns, IA recommendations
View detailed guide →
Diary Studies
When to use: Understand behaviors over time in natural contexts
Participants: 10-20 users
Duration: 1-4 weeks
Output: Contextual insights, behavior patterns, pain points
View detailed guide →
A/B Testing
When to use: Compare design variations, optimize conversion
Participants: Thousands (live traffic)
Duration: 1-4 weeks until statistical significance
Output: Performance metrics, winning variant, confidence intervals
View detailed guide →
Contextual Inquiry
When to use: Observe users in their natural environment
Participants: 6-10 users
Duration: 2-4 hours per session
Output: Workflow understanding, environmental factors, opportunities
View detailed guide →
Focus Groups
When to use: Explore attitudes and opinions (use sparingly)
Participants: 6-10 users per group
Duration: 90-120 minutes
Output: Group perspectives, initial reactions, discussion themes
View detailed guide →
Note: Focus groups can be influenced by groupthink. For unbiased
individual perspectives, consider user interviews instead.
Method Selection Framework
Discovery Phase
Goal: Understand the problem space and user needs
User Interviews - Deep understanding of user contexts

Diary Studies - Track behaviors over time
Surveys - Validate assumptions at scale
Design Phase
Goal: Generate and refine design solutions
Card Sorting - Organize information architecture
Tree Testing - Validate navigation structure
Prototype Testing - Test low-fidelity concepts
Preference Testing - Compare design alternatives
Validation Phase
Goal: Test and optimize final designs
Usability Testing - Identify interface issues
A/B Testing - Compare design variations
Surveys - Measure satisfaction and performance
Analytics Review - Track behavioral metrics

Participant Recruitment
Screen carefully - Ensure participants match target users
Avoid bias - Don't recruit friends or family
Offer compensation - Respect participants' time
Diverse representation - Include various abilities and backgrounds
Over-recruit by 20% - Account for no-shows
Research Ethics
Informed consent - Explain purpose, usage, and privacy
Privacy protection - Anonymize data, secure storage
Right to withdraw - Participants can stop anytime
Accessibility - Accommodate various needs and abilities
Fair compensation - Pay promptly and appropriately

Best Practices
Planning
Start with clear research questions
Define success metrics upfront
Budget adequate time for analysis
Involve stakeholders early
Conducting Research
Build rapport with participants
Ask open-ended questions
Listen more than you talk
Observe non-verbal cues
Take detailed notes
Analysis
Look for patterns across participants
Distinguish between observations and interpretations
Rate severity of findings
Connect findings to recommendations
Sharing Insights
Tailor presentations to your audience
Use participant quotes and video clips
Make recommendations actionable
Track impact of research
Common Pitfalls
Leading Questions
❌ "Don't you think this button is hard to find?"
✅ "What are your thoughts on this interface?"
Small Sample Sizes
❌ "We interviewed 2 users and they both liked it"
✅ "We interviewed 8 users and identified consistent patterns"
Confirmation Bias
❌ Only sharing findings that support your hypothesis
✅ Report all findings, even those that contradict expectations
Research Without Action
❌ Filing away research reports without implementation
✅ Create action plans and track outcomes
