Médiamétrie, a trusted, neutral and independent third party, relies on its data expertise to guide media players in evaluating their data.

Data Checking establishes quality indices for a database by cross-checking it with data from Médiamétrie reference panels

  • Validate the quality of a database with two quality indices
  • Compare socio-demographic criteria, such as gender and age, with those of the Médiamétrie reference panel base

Data Checking croise la Data éditeur avec la Data déterministe, réellement observée et auditée par le CESP, des panels de référence Médiamétrie.

Deux Indices de Qualité :

  • L’Indice Kappa. Il mesure la concordance entre deux qualifications de la même variable, par rapport au hasard. Il permet également d’établir une norme de comparaison entre plusieurs bases.
  • Le Taux de Concordance Global et Détaillé. Il est le résultat de la concordance parfaite entre un critère observé dans la base analysée et la donnée correspondante dans la Base de Référence Médiamétrie Data Checking.
