Eight Laws of Statistics

Statistics doesn’t have a Magna Carta, constitution, or bill of rights to enumerate laws, guiding principles, or limits of power. There have been attempts to articulate credos for statistical practice. Two of the most enduring ones are based on the work by Robert P. Abelson, a former statistical professor at Yale. If Abelson wasn’t the

Sample Sizes for Comparing SUS to a Benchmark

The System Usability Scale (SUS) has been used in industrial user experience research since the mid-1980s.

But statistics isn’t just a formulaic process where you enter data and are told what to do. Statistics should guide, not dictate, decisions. In making decisions, though, there are different styles of interpreting data. Although a lot of people think statistics

Measuring Tech Savviness

What is tech savviness? While it might be hard to define, you probably know someone whom you consider tech savvy—they might even be your go-to person for solving tech issues. Or maybe you know people who aren’t tech savvy and struggle with all technology. But why should UX researchers care? The concept of tech savviness

It’s used widely in benchmark tests of software products to generate an overall score of perceived usability. We regularly collect SUS scores for dozens of consumer and

Completion Times and Preference for Sliders vs. Numeric Scales

In earlier articles, we investigated the effects of manipulating item formats on rating behaviors—specifically, we compared sliders to traditional five-point and eleven-point radio button numeric scales. For those analyses, we collected data from 212 respondents (U.S. panel agency, late January 2021) who used radio buttons and sliders to rate online shopping websites (e.g., Amazon) and

Sliders versus Eleven-Point Numeric Scales on Desktop and Mobile Devices

Adding more points to a scale can increase its reliability and sensitivity. But more points also take up additional screen real-estate space. Imagine twenty or a hundred points displayed on desktop or, even worse, on mobile. One recent digital alternative, allowing for nuanced ratings using the same screen real-estate as a traditional scale, is the
