In this article, we explain why taking the median of rating scale data is a poor practice. measuringu.com/means-vs-medi…
For #UX researchers working in contexts with atypical standard deviations for the SUS, we describe a simple way to increase or decrease tabled sample sizes for comparison tests. measuringu.com/sample-sizes-…
In an experiment comparing #UX ratings with standard numeric scales and star scales, numeric means were about the same whether they were presented first or second, but star ratings were more affected by presentation order. measuringu.com/numbers-versu…
Every few years, we work with UXPA to survey the #UX community regarding compensation, skills, and work composition. Here are compensation highlights and our 2026 salary calculator. measuringu.com/salary-survey…
It’s important in #UXresearch to collect measures of prior experience, including frequency-of-use. measuringu.com/how-to-report…
Because there is no compelling reason to settle on just one rule for the number of response options, different researchers may make different decisions. If you need to compare five- and seven-point data, don’t despair—interpolate! measuringu.com/convert-point…
In a study of likelihood-to-recommend and likelihood-to-discourage, we found NPS Promoters are more likely than Detractors to have low ratings of likelihood-to-discourage. measuringu.com/relationship-…
We’ve developed methods for the comparison of Net Promoter Scores with benchmarks. measuringu.com/nps-benchmark…
We ran two studies (with 1749 participants across 18 products) to determine the best method for constructing NPS confidence intervals. We recommend the adjusted-Wald method. measuringu.com/nps-three-con…
We often think of Think Aloud as a single method, but there are many ways to think aloud. measuringu.com/many-ways-of-…
Despite its known potential for overlaps and gaps in the classification of UI problems, interrater agreement (reliability) for heuristic evaluation was comparable with those reported for the CUP and OSUDC methods. measuringu.com/frameworks-fo…
Mobile apps are big business, so it’s important to have a method to measure the #UX of mobile apps that is quick to administer and easy to interpret. measuringu.com/how-to-score-…
One prominent scholar has said the NPS is “widely discredited in the academic literature.” We reviewed more than 20 academic papers and found qualification, not discrediting, of the NPS. measuringu.com/nps-discredit…
NPS designations of detractor and promoter are based on referral and repurchase behaviors and the sharing of negative comments, but some critics are not convinced. measuringu.com/detractors/
Randomizing tasks minimizes unwanted effects that can distort your data, like participants learning or simply being fatigued. measuringu.com/scientific-th…
Small changes to survey items can have big impacts on responses. Does changing the wording from “will recommend” to “would recommend” have an impact? measuringu.com/will-would
Responses to the NSAT are based on a four-point scale, from “very satisfied” to “very dissatisfied.” Four points is not a lot for a single item measure, but it at least captures intensity, unlike a three-point scale. measuringu.com/microsoft-nsa…
Our investigation of how well digital twins predict human SUS scores for business software found average AI errors of 10 points with measurable differences in AI and human distributions. measuringu.com/digital-twins…
