Our proprietary research technology has been designed to provide a range of data validation methods for assessing the validity of responses and those who are not providing due consideration to the survey. As online research does not allow respondents to be physically monitored, we have developed a number of techniques, detailed below which assist us to identify when data is invalid or unusable.
This assessment is conducted as data is being collected and during data processing once a project closes. Data which clearly indicates poorly considered, inconsistent, rushed and confused input is flagged and may be removed from the final data set.

In addition, participants who are supplied to usvia external sources are also screened thoroughly. Those contributionsthat are deemed invalid on two or more occasions are added to a black-ban listing managed within our system, thus preventing them from participating in further research conducted by i-Link.
In the same way, we compile a history on all i-Linkpanel respondents and can determine those who have been invited to participate in a set number of our surveys. Although rare, our system will block entry to respondents who have previously completed more than 3 surveys in a 6 month period.
