  • Get excited to build the authority and influence of a designer who backs qualitative user insights with hard, statistical evidence. A classic UX design study by Bailey and Wolfson found that users complete their task 87% of the time when their first click on a website leads down the right path, but just 46% of the time when it leads down the wrong one. A first-click test with dozens of users reveals where your navigation is leading them down the wrong path, so you can fix it before it translates to lost conversions. That's the power quantitative research gives you. You can surface and confirm user behavior at a scale your qualitative work cannot, tie your design decisions to business outcomes, and settle conflicting feedback or too many ideas.

  • Prove the return on investment (ROI) of your design decisions to stakeholders when you have more data and confidence than qualitative methods alone could ever give you. Whether you're switching into a design career or stepping into a senior role, this course takes you from the foundations through to running surveys, early-design tests, analytics, and A/B tests in real projects. You'll get a practical,formula-free grounding in statistics, significance, and sampling.

  • Make yourself invaluable when you can choose the best quantitative method for the situation, apply it effectively, analyze the results, and turn the numbers into confident decisions. You'll build versatility as you master surveys, tree testing, first-click testing, web and app analytics, and A/B and multivariate testing. Finally, you'll use triangulation to validate your qualitative insights before you commit organizational resources. As AI becomes standard for processing data, your ability to frame the right problems, interpret results through a human lens, and translate insights into action is the human-centered skillset hiring managers want to see.

  • Gain confidence and credibility as you strengthen your research toolkit and can make the case for using it. You'll learn to screen participants, spot disengaged ones, and write survey questions that minimize bias. You'll use standardized usability questionnaires like SUS and WAMMI to benchmark your product against industry data. For analytics, you'll work through Jansen's four-step process in Google Analytics: identify the stakeholders whose cooperation you'll need, define primary goals and conversions, identify your most important visitors, and set KPIs that hold up over time. On the statistics side, you'll learn hypothesis testing and the null hypothesis: the logic behind every test you'll run. You'll also gain a clear decision process for choosing one based on your data type. Since most UX data is categorical (conversions, clicks, choices), you'll focus on Chi-Square and Fisher's exact, with the t-test and Mann-Whitney U for numerical cases like task times.

  • Craft your portfolio with an optional, multi-part project. You'll design and run a real survey, an early-design test, an analytics analysis, and an A/B test on a website or app of your choice. Throughout the course, you'll get downloadable resources, including a Likert Scale Spreadsheet, a Data Types and Statistical Tests Template, and a Survey Question Tips Template, so you can immediately apply what you learn.
