When explicitly offered the economy as a response, more than half of respondents (58%) chose this answer; only 35% of those who responded to the open-ended version volunteered the economy. Moreover, among those asked the closed-ended version, fewer than one-in-ten (8%) provided a response other than the five they were read; by contrast fully 43% of those asked the open-ended version provided a response not listed in the closed-ended version of the question. All of the other issues were chosen at least slightly more often when explicitly offered in the closed-ended version than in the open-ended version. (Also see “High Marks for the Campaign, a High Bar for Obama” for more information.)
For example, while many packages provide the ability to preview what a survey looks like on a desktop or a mobile device, Qualtrics does simultaneous and synchronized previews of both, side by side. And there was simply nothing in any other package that could compare to the power of its "Survey Flow" capability for tracking what can be a twisted path through complex surveys. Qualtrics also has an excellent reporting feature, including a number of advanced statistical analysis and semantic analysis of textual responses as well as robust report formatting.
“I participated in an in-home product trial study. A coffee machine company sent me one of the coffee makers along with about 200 coffee pods. I received $7 for completing 3 short surveys. Plus, after the study, the company said I could keep the coffee maker. So, I got like 4 mos of coffee for everyone in my household, a free coffee maker and $7!” - David W.
