The use of internet access panels for sampling and questioning is a relatively new research technique. It will take some time before uniform quality standards can be defined and adopted across the industry. In the early stages of a methodological development there will be many different approaches attempted by research suppliers.
Research buyers who wish to get a more thorough understanding of the methodology offered by a research provider can use the following set of 25 questions as the basis of a discussion of methodology.
Reputable suppliers with established methodologies and active panel management policies will be able to provide answers to these questions. The decision to go ahead or not can then be made on an informed understanding of the approach being offered and its likely quality.
Yes, our online panels are actively managed.
Via our panelist portals
www.opinion-people.com we build strong long-term relationships with our panelists by engaging them to take part in community events and quick polls, view content, update their profiles...
As a leader in high quality online fieldwork we believe that this is fundamental to ensure that the data we deliver is reliable and valid.
All panel-counts communicated by ODC Services are based on the number of active panel members.
We define an active panel member as a person who has registered at opinion people and has completed our basic profile. He/She has answered at least one survey within the past 12 month OR has indicated to ODC Services that he/she wishes to remain a member of the panel. Furthermore he/she must have updated his/her own profile at least once within the past 12 month.
At opinion-people 100% of our recruitment activties are "on-invitation only". This keeps the risk of multiple-registration, panel-overlap and so called "Incentive-Hunters" low and allows us to control the panel distribution.
ODC Services retains documentary proof of how each panel member was recruited. A statistic of what percentage of the panel was recruited via different sources is available at any time.
The opinion people panel is recruited via various online and offline sources such as Direct Mailings, CATI-Recruitment, On-Site-Recruitment...
Yes, all our panel-members have registered at opinion-people via a double-opt-in process.
Every person who is invited to join our panel gets a personalized invitation-code which allows him/her to register at opinion-people.
After the first registration step this person gets a confirmation email and only upon confirmation a person can answer our basic profile, which allows them to become an active panel member.
