Many of us in marketing research have been deploying web surveys for over ten years, and web surveys are, by far, the dominant mode of data collection in our industry nowadays. But our techniques and methods are an amalgam of practices adapted from other data collection modes, learned in part through trial and error, and taught to others through channels more akin to oral traditions. So it is helpful when our academic colleagues manage to document and codify the art and science of what we do. (more…)

Even if you are not involved in political polling, it is worth paying attention to the methods and best practices of political pollsters. One reason is that few other areas of research offer a way to completely validate one’s methods. Pollsters are using sampling and survey methods to predict the behaviors of a much larger population. Then in just one day that population behaves, we get a near-perfect count of exactly how they behaved, and we know whether the methods worked.
Several industry colleagues have recently been debating the merits of calculating and reporting “margins of error” in political polling, and pointed us to some surprising data from The New York Times: (more…)

Over the last few years we have wondered whether spreadsheet software like Excel will soon make statistics software like SPSS or SAS obsolete.
Spreadsheets have amazingly powerful and often intuitive capabilities. They have many of the statistical functions we use every day. Younger people entering our profession rarely know programs like SPSS or SAS, and we see them turning to Excel to generate frequencies, calculate means and proportions, create charts from data, and so on. The same goes for our customers. Many do not have statistical software, so when they need numbers and statistics, they often work in Excel.
But Versta Research continues to invest in advanced statistical software rather than doing our work in Excel for three important reasons: (more…)

One powerful way to gain visibility and credibility in your marketplace is by sponsoring survey research that documents problems and solutions in areas where you have expertise. To be successful, it requires (1) rigorous research carefully designed to uncover the right topics, and (2) savvy PR work that uses data to tell a credible and compelling story.
The Public Relations Society of America (PRSA) and the American Statistical Association have just published a handy guide for PR professionals that outlines best practices for using, interpreting and reporting statistics in press releases and other PR materials. Some of those best practices include the following: (more…)

Many of us have uneasy feelings when reading statistics that presumably apply to ourselves and our own lives. Often the statistics do not seem to “fit” and seem to misrepresent the lives of real people from which the statistics are derived. It is with good reason that we chuckle when someone tells us that the average U.S. household has 0.64 children in it.
We were reminded of this upon hearing prominent news reports a few days ago that the average household income in the U.S. has fallen by about 10% in the past decade, most of it happening since the start of the recession four years ago. But does that mean most Americans’ incomes are falling? No. Though it is hard not to think so given how the data are being presented and reported.

Monty Hall in Let's Make A Deal
The hardest part of quantitative market research is not that it involves numbers, math, or even statistics, but that it involves complex problems in probability.
Over the past several years, psychologists have been documenting how difficult it is for us humans to solve even “simple” probability problems. One fascinating example is a puzzle known as the Monty Hall dilemma based on the 1960’s game show Let’s Make A Deal. Monty would offer his contestants three doors to choose from, one of which had a valuable prize behind it. After the contestant chose, Monty would open one of the other two doors, deliberately choosing one that had no prize behind it. Then he offered the contestant an option of staying with the original choice, or switching to the other unopened door. Which should the contestant do? (more…)

This year Ogilvy & Mather is launching a unit within its agency that focuses on cross-cultural marketing as opposed to multicultural marketing. This is an important shift in how to think about multiple markets and segmentation, and consistent with what we at Versta have been seeing in our research for quite some time. (more…)

Versta Research just hit a magic number: 100. That’s the number of articles we have written to help our clients and their colleagues keep abreast of important trends in market research. If your market research supplier is not providing ongoing thought leadership in design, methods, and analytics, then what are the chances they are bringing ongoing and deep insight to your specific research needs?
To celebrate, we’re serving up a sampler of our five best articles. How did we decide they are the best? Our clients told us. These are the articles that they write to us about, forward to their colleagues, and for which they return to our website time and again. These are also the articles for which we get requests for print-ready PDF versions. (Just let us know if you want one!) (more…)

Learning the math behind market research is not easy because there is no programmatic way to master it as a body of learning. It is not like algebra, geometry, calculus, or statistics in high school or college. It is complex and multifaceted and draws upon nearly every area of theoretical mathematics, but it must be continually adapted to the needs and practical problems of measuring and predicting customer behaviors and attitudes.
So it requires both (1) a rigorous foundation in mathematics and (2) years of experience to understand how it gets re-worked and applied to the real-life questions of market research. And even the rigorous foundation needs to be continually reinforced and expanded as the scope of our capabilities expands. Twenty years ago, who would have thought that Bayesian statistics and Monte Carlo simulations would become so central to our work? (more…)

Last quarter we wrote about Magic Numbers in Market Research—those arbitrary rules of thumb and cut-off points we use when quoting things like minimum samples sizes or how many people to include in a focus group. Presto! Like magic, the issue appeared in the New York Times a few weeks ago, this time related to a dispute about the best way to statistically test for the existence of ESP.
The backstory: A respected academic journal in social psychology published an article showing data that suggests ESP exists. Horrified, some researchers argued that psychologists were using old-fashioned inferential statistics when they should be using modern-day Bayesian statistics. Here is a link to the article, if you’re interested. Unfortunately, it does a lousy job explaining what Bayesian statistics is.
But fortunately, in response, the editor in chief of The Annals of Applied Statistics submitted a letter to the New York Times clarifying that all statistics ends up relying on arbitrary magic numbers: (more…)
