Quantifying the User Experience: Practical Statistics for User Research

You’re being asked to quantify usability improvements with statistics. But even with a background in statistics, you are hesitant to statistically analyze the data, as you may be unsure about which statistical tests to use and have trouble defending the use of the small test sample sizes associated with usability studies.

The book is about providing a practical guide on how to use statistics to solve common quantitative problems arising in user research. It addresses common questions you face every day such as: Is the current product more usable than our competition? Can we be sure at least 70% of users can complete the task on the 1st attempt? How long will it take users to purchase products on the website? This book shows you which test to use, and how provide a foundation for both the statistical theory and best practices in applying them. The authors draw on decades of statistical literature from Human Factors, Industrial Engineering and Psychology, as well as their own published research to provide the best solutions. They provide both concrete solutions (excel formula, links to their own web-calculators) along with an engaging discussion about the statistical reasons for why the tests work, and how to effectively communicate the results.

    *Provides practical guidance on solving usability testing problems with statistics for any project, including those using Six Sigma practices

    *Show practitioners which test to use, why they work, best practices in application, along with easy-to-use excel formulas and web-calculators for analyzing data

    *Recommends ways for practitioners to communicate results to stakeholders in plain English

      This review is from: Quantifying the User Experience: Practical Statistics for User Research (Paperback)

      Whether you’re conducting large sample research projects or small ones, “Quantifying the user experience” is the most comprehensive and pragmatic statistical handbook I’ve seen that systematically explains various statistical methods for drawing reliable conclusions or determining the optimal sample sizes. Great resource for conducting surveys, A/B tests or (and here they really shine) small sample usability testing projects.

      Rather than starting with a description of various statistical theories, the authors begin with specific user research scenarios and then introduce the theoretical methods they feel most suitable for planning or analyzing these scenarios. They don’t shy away from sharing their pragmatic preferences for particular methods, based on their own experience working in the field.

      I find the book useful also beyond user experience testing scenarios – it is a great resource for any user-oriented research, including various types of marketing research.

      This review is from: Quantifying the User Experience: Practical Statistics for User Research (Paperback)

      I’ve been waiting for a book like this for a long time. Most of my user research consulting work is qualitative, but I’m periodically faced with running benchmark usability studies or designing other quantitative user research projects that involve inferential statistics. No more dusting off old college stats textbooks. This book and its Excel and R Companion book are a one-stop shop for determining appropriate quantitative research methods and statistical tests to use in UX work. The authors draw many practical examples from usability studies, tie statistical theory together with practice when using small sample sizes, and even include a crash course in statistical concepts as an appendix. I’ve been a fan of Jeff Sauro’s website for several years now and am very pleased that he and Jim Lewis have authored this exceptional resource.

      This book will be very useful for all the designers that wish to bring scientific validity in their services and products evaluations (and there is a lot of work ahead in this domain…), thanks to all the interesting indications and computations it contains.
