Princeton National Surveys Leverages Powerful Features of Snap Survey Software

Guest Post: Learn how Princeton National Surveys leverages the powerful features of Snap Survey Software to target and balance respondent samples

A Snap Surveys client for over ten years, Princeton National Surveys (PNS) leverages powerful features of Snap Survey Software to target and balance respondent samples. The advanced technology offered by Snap Surveys enables PNS to collect more complex sample combinations than what is possible with less sophisticated do-it-yourself online survey apps.*

Princeton-National-SurveysSurveys deployed on Snap WebHost, Snap’s online survey management and reporting system, can be programmed with interlocking quotas based on any number of questions, including numeric-entry questions (such as ZIP Code), and the detected screen size of a respondent’s device. The key to this technique is Snap’s feature called derived variables. Using derived variables in Snap Survey Software, a survey designer can write expressions to combine, convert, segment, or calculate responses. Logical, literal, numeric, date, and time expressions are supported.

Snap describes their interlocking quotas using a simple two-question example in this helpful worksheet: Interlocking Quotas in Snap WebHost

PNS has successfully implemented surveys using Snap’s technology to simultaneously qualify, monitor, and gate highly precise, low-incidence samples, enabling us to improve sample quality, reduce costs, and curtail overage waste.

For example, a marketing research study required a sample with equal numbers of respondents who purchase the client’s test brand and who purchase competing brands, while balancing the proportion of males/females and other demographic characteristics. A derived variable was used to pinpoint the test brand with one code and group competing brands into another single code.

Respondents who meet the qualifying criteria for participation in an online survey hosted on Snap WebHost, but fall into a filled quota group can be sent to the URL of a specified web page. This URL can include static text and dynamic elements from survey variables, such as an anonymous identification number, that can be received by scripts on active server pages (ASP) (see: Snap 11 Help). PNS uses this method to publish surveys for respondents recruited via third-party panel suppliers.

With the flexibility to define quota groups using Snap’s derived variables, PNS always “sticks the landing” on our balancing acts.
