As a reminder, Data Checking validates the quality of databases belonging to publishers, operators and advertisers by combining them with Médiamétrie’s “reference panels”, which contain 300,000 contacts categorised by age, gender, SPC, etc.  This solution generates two indicators:

• the quality diagnosis, or “Kappa number” is established by variables that allow to calibrate the quality of the studied database by comparing it to a standard, on any criterion shared by the two databases;
• the strict Direct Agreement Rate with the Médiamétrie reference database.

Amongst other things, Data Checking is a means of prioritising internal databases on the basis of their quality, as well as checking and comparing the quality of databases belonging to partners or suppliers. It can even help to improve their data, since it only retains the most relevant databases.

Estelle Duval, Data Business Director at Médiamétrie, commented:

“To our customers who have chosen the Data Checking solution, the Médiamétrie “label” represents a guarantee of quality. This award is confirmation that a tool such as Data Checking is necessary to develop market confidence. Accordingly, Médiamétrie and the Data Committee are pushing ahead with the goal of establishing a Data Quality standard in France through a trusted, independent third party. At the same time, we are working alongside our customers on tailored projects to qualify and enrich the data.”
