In the recent issue of User Experience magazine, a publication of the User Experience Professionals’ Association (UXPA), GfK’s Korey Johnson examines Jeff Sauro and James R. Lewis’ book, “Quantifying the User Experience: Practical Statistics for User Research.” As the second book co-authored by Sauro and Lewis, this text provides a practical guide for effectively quantifying usability improvements with statistics.
In his review, Johnson commends the authors for their two-fold approach of describing both practical and theoretical aspects of statistical measurement. He also stresses the book as a valuable resource for researchers to better identify and apply quantitative methods during user experience (UX) research.
“Those of us tasked with quantifying the user experience know that convincing stakeholders we are using the correct measures is just as difficult, if not more so, as selecting the measures themselves,” says Johnson. “The authors provide readers with the rationale needed to make informed decisions about the application of statistical measures, but they also provide sufficient detail to understand both sides of every argument so that when questioned, researchers have the information needed to defend the validity of their results.”
Focused on careers in user experience, the UXPA magazine issue also includes articles, recommendations and resources for successfully navigating the UX profession.
Johnson is an associate director with GfK’s User Experience team and a leading expert in human factors research and usability verification and validation for medical devices. With a strong background in behavioral research design, methodology, and analysis, Korey has managed or contributed to over 100 UX research studies related to medical devices, in-vehicle navigation systems, and web applications.
