Title 28 Questions to Help Buyers of Online Samples
Source ESOMAR (2012)
Year 2015
Access date 31.10.2015


The new 28 Questions to Help Buyers of Online Samples guide, is a revision of ESOMAR’s 26 Questions and is also designed to provide a standard set of questions a buyer can ask to determine whether a sample provider’s practices and samples fit with their research objectives. The questions help research buyers think about the issues relating to online samples.

We hope that companies post their own answers to the new 28 questions online to increase transparency and enable buyers to compare services of different suppliers.

Pete Cape, Global Knowledge Director, SSI and Editor of the text says: "The old questions were grounded in a world that saw panelists being communicated with via email about projects - no mention of routers or the blending of multiple disparate sample sources. We needed to change to reflect this and took the opportunity to update and revisit our question set. Our new 28 Questions represent evolution not revolution and remain the key questions to ask your supplier of online samples."
