Does Thinking Aloud Uncover More Usability Issues?

One of the most popular UX research methods is Think Aloud (TA) usability testing. In TA testing, participants speak their thoughts while attempting tasks. The process helps researchers identify usability problems and potential fixes. But is the process of thinking aloud necessary to uncover problems and insights? Earlier, we investigated the effects of TA on

When and Why to Use a Click Test

Where will people click on a webpage or app? It’s a good question because knowing where people click can help designers understand how functions and content help or inhibit users from accomplishing their tasks.

Measuring Tech Savviness with Technical Activity Checklists

UX research is geared primarily toward understanding how to improve the experience of products, websites, and software. The intent is not to assess people but to use people to assess product experiences. But people’s ability to solve technical problems—what we often loosely refer to as tech savviness—can confound our research findings. That is, including only

Examining the Evaluator Effect in Unmoderated Usability Testing

If different researchers conduct a study, will they identify different problems? While it was originally controversial, the evaluator effect is now well-established in the field of UX research.

Sample Sizes for Rating Scale Confidence Intervals

Sample size computations can seem like an art. Some assumptions are involved when computing sample sizes, but it should be more math than magic. A key ingredient needed to cook up a sample size estimate is the standard deviation. You need yeast to make bread, and you need a measure of variability to make an

Initial Validation of Tech-Savvy Measures

How do you measure tech savviness? For several years (since 2015), we’ve been on a mission to develop a valid and practical measure. In our earlier articles, we have Reviewed the literature. We reviewed the literature on tech-savvy measures and found three key approaches to measuring tech-savviness by assessing (1) what a person knows, (2)

How to Estimate the Standard Deviation for Rating Scales

The standard deviation is the most common measure of variability. It’s less intuitive than measures of central tendency such as the mean, but it plays an essential role in analysis and sample size planning.
