Versta Research has just published is spring 2014 newsletter which features a short video on how to do pricing research. If you ever work with price and demand data, and need to figure out the optimal price for your product or service, here are two great tools worth knowing about: 1. PowerPoint (yes, that says…
I just read an online interview with Bob Muenchen, author of R for SAS and SPSS Users. He nicely describes an important aspect of R that I found to be one of the weirdest and most difficult to grasp, but once I “got it,” fell in love. Quoting at length:
Progress bars that show respondents how far along they are in a survey have become standard in our industry. But are progress bars a documented “best practice” for survey research, or just another convention? A recent article in the Social Science Computer Review offers a meta-analysis of 32 field experiments designed to see whether progress…
I’m not sure if this cartoon is funny because I don’t really get it. But it was interesting enough that I started thinking about the null hypothesis, and what it means, and how statistics is changing so quickly that “the null hypothesis” we learned about in our classes may soon feel like an odd artifact…
Every year I offer my top picks for summer intensive training courses on research methods, and usually I point to several universities for the sake of options and a full range of methods. Well, this year I am pointing to just one. I looked at the course listings at the University of Michigan’s Survey Research…
Last week we wrote about the optimal number of benefits, features, or claims you should make in your marketing materials. Research shows that three maximizes the impact because it aligns with a buyer’s sense of data sufficiency. Going beyond three invites skepticism because it reminds buyers that the message is “just marketing,” not information. So…
As we get further along in our careers most of us get further away from the nitty-gritty of data collection, data coding, and sometimes even data analysis. But I always feel nervous about that distance, and usually want to take a quick scan through the raw data myself. I want to see all those rows…
Versta Research’s winter newsletter comes out next week, which will focus on some new approaches to faster (and cheaper) market research. In the meantime we have been thinking a good deal about where to invest in new methods and innovation during the coming year so that we continue to make our work better and smarter…
The Associated Press (AP) announced last month it is moving all of its public opinion polling from phone surveys to online surveys. This is progress, because over the last decade AP has been one of a handful of media holdouts (along with ABC News and The New York Times) who have insisted that only phone-based…
The purists in the polling industry who have always insisted that only probability sampling is valid may finally be accepting that their methods are dead. This is one happy conclusion I draw from the debate over AAPOR’s recent task force report on non-probability sampling, which is nicely summarized (and debated) as the lead article of…
