Sample Sizes for Comparing UX-Lite Scores
The UX-Lite® is a relatively new metric, but it is versatile, short, and increasingly popular for UX research. It measures perceived usability and usefulness with just two items. But if you’re using the UX-Lite to compare products or to see whether you’ve improved over time, what sample size do you need? Yes, the sample size
UX and NPS Benchmarks of Clothing Websites (2026)
It’s hard to beat the convenience of shopping for clothing online. You don’t have to worry about when the store will close or finding parking, and getting a price comparison with other stores is just a few clicks away. On websites, you can easily search for clothing using keywords, and it’s simple to see the
UX-Lite Sample Sizes for Comparison to a Benchmark
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
UX and NPS Benchmarks of Mass Merchant Websites (2026)
People spend a lot of money (and time) on online purchases, most of that on what we call mass merchant retail websites. The US Census Bureau estimates Q3 2025 retail e-commerce sales at $310B (15.8% of total retail sales that quarter). Spending continues to grow but is tempered by inflation, making shoppers more economically pessimistic
UX-Lite Sample Sizes for Confidence Intervals
The UX-Lite® is an increasingly popular UX metric. There’s a reason for its popularity. It’s a simple two-item questionnaire that measures perceptions of the user experience of any interface (product, app, website). Its two five-point items are combined and scaled to generate an overall score and subscale scores on ease and usefulness from 0 to
How the SEQ Correlates with Other Task Metrics
While task completion and task time are the default choices for measuring task effectiveness and task efficiency, the methods used to capture people’s feelings about an experience certainly seem more varied. But after measuring post-task perceptions for decades, we’ve found that a simple seven-point item does a good job of capturing not only perceptions of

How Much Does Satisfaction Correlate with Ease?
Satisfaction is different than ease of use. But they are both attitudes. We provided the conceptual foundation for what satisfaction is, how it differs from perceived ease of use, and how both can be collected at the overall product level (also called the study level) or at the task level. So, while we know they
What Are UX Research Deliverables?
As professionals, we’re judged on what we produce. So-called deliverables are the artifacts produced by researchers. But what are UX research deliverables? Deliverables are almost always a digital record of inputs, outcomes, and recommendations in a document or presentation. But delivering documents and presentations fits the description of just about all knowledge worker output, so
What Is the Difference Between Ease and Satisfaction?
“Satisfaction” is used rather broadly in vernacular speech. We can feel satisfied with a meal, a movie, or a moment. Our feeling of satisfaction blends utility (it fed me), affect (I enjoyed it), and expectation (it lived up to or exceeded what I wanted). The dessert, the movie ending, or the moment can all be
Rake Weighting: How to Weight Survey Data with Multiple Variables
Having a representative sample is ideal when making inferences about your customer or user population. In practice, it can be difficult to recruit the right proportion of respondents, leaving your sample out of balance with the population. One way to adjust for being off balance is to weight the data you collected to get the
What Metrics Has MeasuringU Created?
At MeasuringU®, we don’t just use UX metrics—we create them. But what have we created, and what have we just used or extended? Across our combined careers, we (Jeff and Jim) have published 16 psychometrically qualified UX metrics (both creating original and modifying existing questionnaires) plus a method for combining prototypical usability metrics, and we
