Usability practitioners have diverse backgrounds. Many don’t have a background in statistics but are being asked to quantify their usability improvements. Even those with a background in statistics are hesitant to statistically analyze their data, as they are often unsure which statistical tests to use and have trouble defending the use of small test sample sizes.

The book is about providing a practical guide on how to use statistics to solve common quantitative problems arising in user research. It will address common questions facing practitioners 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 practitioners which test to use, 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.
