Workshop Description
The ability to identify meaningful relationships between variables gives UX professionals a new, rigorous source of insight. Learn to surface the hidden relationships that matter—like whether satisfaction actually predicts retention, or if perceived usability correlates with conversion. In this hands-on, 2-hour intensive, you'll master the fundamentals of correlation analysis to answer the "what relates to what" questions that stakeholders actually care about.
This hands-on workshop focuses on correlation analysis for survey data, teaching you how to select the appropriate correlation statistic for your variable types, interpret results accurately, and communicate findings with confidence. Stop presenting isolated metrics. Start revealing the relationships that drive product decisions.
You'll learn how to merge survey data with internal business data—like revenue, retention, or user characteristics—to create a richer picture of your users and outcomes. From understanding when to use Pearson's r versus Spearman's ρ, to spotting misleading results in very large datasets, you'll gain the knowledge and practice to analyze relationships in your survey data with credibility and precision.
Workshop Format
At the UXR Institute, we emphasize applied learning over theory in isolation. In this live, guided workshop, we’ll use survey datasets to explore how variable type and measurement level determine the right correlation test to use.
You'll start by identifying which questions from a survey produce continuous, ordinal, or dichotomous data—and how each links to a specific correlation method. Then, we’ll discuss merging multiple datasets, provide R code for running correlations with significance testing, describe how to interpret correlation matrices, and interpret the meaning and significance of your results. You’ll learn what a small, medium, and large correlation looks like.
Every exercise connects directly to real-world UX research questions, such as "Does user satisfaction correlate with retention?" or "Does perceived usability align with higher engagement or sales?" You'll leave with a complete, repeatable workflow for conducting correlation analysis on survey data.
Tools used: R code will be provided. It won’t be run live and you will not need to run anything.
What new skills will I gain from this workshop?
You'll learn how to plan and design surveys to explore correlations. You’ll develop a clear, structured process for performing correlation analysis with survey data—from study planning through statistical interpretation. You'll learn to handle different data types confidently, apply R code for real analysis, and integrate survey results with business metrics for richer, evidence-based insight.
Move beyond descriptive reporting. When you can demonstrate that perceived ease-of-use correlates with actual feature adoption, or that satisfaction scores correlate with retention, you're not just sharing opinions—you're revealing strategic patterns that drive product decisions.
How will this workshop help my career?
Correlation analysis is one of the most common yet misunderstood techniques in UX research and data science. This workshop helps you bridge the gap between attitudinal and behavioral data, enabling you to deliver more persuasive, data-backed insights.
Stakeholders pay attention when you connect attitudinal measures to business outcomes. This workshop gives you the statistical credibility to do that rigorously. You'll stand out as a researcher who not only collects survey data but interprets it meaningfully and communicates results with confidence—moving from reporting what users say to revealing what it means for product success.
Who is this workshop for?
This workshop is ideal for:
UX researchers who collect and analyze survey data
Researchers who want to connect survey insights with behavioral or business outcomes
Professionals comfortable with basic data concepts who want to strengthen their statistical reasoning and analytic fluency

Learning Outcomes
By workshop completion, you will confidently:
Identify which correlation statistic fits different survey data types (continuous, ordinal, dichotomous)
Link survey-based research questions to appropriate correlation analyses
Understand the benefits of merging survey and internal datasets for comprehensive analysis
Have R code to execute correlations with significance testing
Interpret correlation findings
Evaluate the strength, direction, and significance of correlations
Recognize and avoid spurious or misleading relationships in bivariate analyses
Report correlation findings clearly and credibly to stakeholders
Overview
Detailed Workshop Outline
Understanding Data Types and Correlation Choices
Review continuous, ordinal, and dichotomous data in survey research
Learn which correlation statistic to use for each:
Pearson's r for continuous variables
Spearman's ρ and Kendall's τ for ordinal data
Polychoric and polyserial correlations for mixed variable types
Point-biserial for one dichotomous and one continuous variable
Understand why choosing the right statistic matters for accurate interpretation
Matching Research Questions to Correlation Analyses
Explore examples of good correlation-based research questions, such as:
"Does an app's ease of use correlate with sales?"
"Does satisfaction relate to retention?"
"Does perceived usability correlate with task completion rates?"
"Which user characteristics relate to higher engagement?"
Learn when correlation is appropriate—and when it's not
Planning Your Study and Hypotheses
At the planning stage before analysis, think about how to combine survey data (e.g., satisfaction, usability, intent) with internal metrics (e.g., revenue, engagement, retention) to answer important UX questions
Identify potential relationships: what variables might be linked to your outcomes?
Consider user characteristics that may cause variation (e.g., demographics, experience level)
Running Correlations in R
Correlation code in R will be provided. It won’t be run live and you will not need to run anything.
Learn syntax for different correlation tests (Pearson, Spearman, Kendall, etc.)
Understanding and Interpreting Results
Interpret correlation matrices and understand what coefficients mean
Learn the difference between positive and negative correlations
Interpret the magnitude of correlation (low, medium, high) and what is "meaningful"
Significance Testing and Reporting
Test for statistical significance of correlation results
Interpret p-values and confidence levels correctly
Communicate significant findings clearly and responsibly
Avoiding Common Pitfalls
Use the correct correlation statistic for the type of data you have
Understand when correlations become less useful
Recognize the potential for spurious relationships in bivariate analyses
Know when to move beyond correlation to more robust modeling
