The UX-Lite® is a relatively new but increasingly popular metric for UX research. Its two items generate an overall score and subscale scores on ease and usefulness from 0 to 100. The UX-Lite predicts future product usage as well as or better than the original and longer Technology Acceptance Model (TAM). The ease score also
AI is rapidly changing. By the time we write about the latest features and performance benchmarks, they are replaced by newer features and benchmarks. But are all those features and benchmarks noticed by users? Perhaps. The speed of change in AI shouldn’t stop us from taking a snapshot of the user experience. Even with rapidly
The word “standardized” conjures memories of high-stakes tests. In the context of UX research, when we talk of standardization, we’re often referring to standardized questionnaires. Standardized questionnaires have gone through the process of psychometric validation. That means the items being used have gone through dozens or hundreds of possible variations, and the final versions are
In the movie 2001: A Space Odyssey (made in 1968), a vision of the future included video conferencing. And 1989’s Back to the Future’s vision of 2015 included not only video conferencing but also getting fired over it. While we may scoff at how hoverboards and flying cars still haven’t arrived, it’s now normal for
One of the more challenging things about learning math in general (and statistics in particular) is how the formulas, often with Greek symbols, translate to things we can see and experience. The abstractness of these formulas often means we just have to take them at face value, believing that someone smarter than us made sure
Who cares what happened 15 or 20 years ago? While technology changes fast, some of the most important questions in UX research are more enduring. Preparing for the future means understanding the past. We’re celebrating our 20th anniversary at MeasuringU (2005–2025). For us, it’s less about popping the champagne and more about reflecting on how
Measuring the user experience starts with UX metrics. But there is no single UX measure—no universal gauge that provides a complete view of the user experience. Instead, we rely on multiple metrics, each offering an incomplete yet complementary perspective. We’ve identified over 70 UX metrics, encompassing action metrics (what people do) and attitude metrics (what
Since its development in the 1980s, System Usability Scale (SUS) score analysis has focused on estimating and comparing means. The mean is one type of average. Would it be more appropriate to estimate and compare SUS medians instead of means? To investigate this question, we analyzed and compared SUS means and medians collected from over
What makes a measure valid? Good intentions? Because someone influential said to use it online? A measure is valid if it can be demonstrated that it measures what it is intended to measure, has the expected alignment of items with factors, and has the expected statistical relationships with other metrics. Its usage also depends on
It’s hard to call a product or app successful if people don’t use it. But how will you know if people will use a product and continue to use it? There’s a strong need to understand technology adoption and usage. The first step in predicting and understanding why people do or don’t adopt tech is
