Censuses, Polls, Surveys, and Questionnaires:
How Are They Different?

Surveys are one of the most popular methods in applied research. While many have argued that surveys are overused, it’s hard to believe that surveys have no place in multi-method UX research. When conducting survey-based research, you’ll often encounter the terms census, poll, and questionnaire used in conjunction with—and often interchangeably with—the term survey. But

Accuracy of Three Ways to Estimate SUS with the UX-Lite

In a previous article, we described three ways to estimate SUS scores from UX-Lite™ (and UMUX-Lite) scores, using either both items (perceived measures of Ease and Usefulness) or the Ease item only: Two-item interpolation: Scaling the mean of both items to a 100-point scale (Lite). One-item interpolation: Scaling just the Ease item to a 100-point

Three Ways to Measure a User’s Prior Experience

Individual differences in behavior and attitude often overshadow the differences in designs. There are many ways to characterize how people differ. But one characteristic that drives both attitudinal and behavioral UX metrics is prior experience. Beyond the more superficial aspects of demographic variables such as age, gender, income, and geography, a person’s experience with an

Campbell’s Law and the Net Promoter Score

To make better decisions, you need data. That’s become a truism. But can the process of using the data lead to bad outcomes? It seems like a hypothetical question, but it doesn’t take long to find a few key metrics that, when tracked, can lead to unwanted outcomes: On-time departures: On-time flight departures for airlines

So, you’re planning to collect data and you want to know whether your Net Promoter Score (NPS) is significantly above 50%. Established benchmarks can help research teams know if they’ve reached acceptable thresholds, such as a high Net Promoter Score (e.g., more than 50%). A high NPS is associated with successful product launches. But an NPS

How Does Statistical Hypothesis Testing Work?

Statistically significant. p-value. Hypothesis. These terms are not only commonly used in statistics but also have made their way into the vernacular. Making sense of most scientific publications, which can have practical, significant effects on public policy and your life, means understanding a core framework with which we derive much knowledge. That framework is called

Leading Vs. Lagging Measures in UX

Driving down the road while only looking in the rearview mirror … that gives you a good idea of where you’ve been, but unless the road behind you is exactly like the one in front of you, you may run into some obstacles, to put it mildly. Safe and effective driving means looking forward and

Confounded Experimental Designs, Part 1: Incomplete Factorial Designs

UX research and UX measurement can be seen as an extension of experimental design. At the heart of experimental design lie variables. Earlier we wrote about different kinds of variables. In short, dependent variables are what you get (outcomes), independent variables are what you set, and extraneous variables are what you can’t forget (to account
