If you took an intro to stats class (or if you know just enough to be dangerous), you probably recall two things: something about Mark Twain’s “lies, damned lies …,” and that your data needs to be normally distributed. Turns out both are only partly true. Mark Twain did write the famous quote, but he
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
The Net Promoter Score (NPS) is widely used by organizations. It’s often used to make high-stakes decisions on whether a brand, product, or service has improved or declined. Net Promoter Scores are often tracked on dashboards, and any changes (for better or worse) can have significant consequences: adding or removing features, redirecting budgets, even impacting
The Net Promoter Score (NPS) is a popular business metric used to track customer loyalty. It uses a single likelihood-to-recommend (LTR) question (“How likely is it that you will recommend our company to a friend or colleague?”) with 11 scale steps from 0 (Not at all likely) to 10 (Extremely likely). In NPS terminology, respondents
There’s no shortage of opinions about the Net Promoter Score. There’s nothing wrong with an opinion. It’s just better when there’s data backing it. Unfortunately, when it comes to opinions about the Net Promoter Score, especially how the underlying question is displayed, the opinions are often based on anecdotes and out-of-context “best practices.” At MeasuringU,
The Net Promoter Score is ubiquitous and may be a victim of its own success. According to the Wall Street Journal, in 2018 the NPS was cited more than 150 times in earnings conference calls by 50 S&P 500 companies. And its usage seems to be increasing. The NPS, like all measures, has its shortcomings
Around a quarter of Americans change jobs each year. For most, that job search happens online. Job related websites are a multibillion-dollar business with plenty of competition. They have made finding and applying for jobs more accessible and easier. However, the process isn’t without issues. Job descriptions can be misleading, and the application process can
In an earlier article, we examined the relationship between NPS and future company growth. We found the Net Promoter Score had a modest correlation with future growth (r = .35) in the 14 industries we examined. In the 11 industries that had a positive correlation, the average correlation with two-year revenue growth was higher at
In an earlier article, we examined the folk wisdom that three-point scales were superior to those with more, such as five, seven, ten, or eleven response options. Across twelve published studies we found little to suggest that three-point scales were better than scales with more points and, in fact, found evidence to show that they
The Net Promoter Score introduced a new language of loyalty. At center stage are the promoters and detractors. These designations are given to respondents who answer the How Likely Are You to Recommend (LTR) question as shown below. But what is the justification for the designations? Were they just arbitrarily created? Do they just
