ECC (External Coincidental Check)

ECC is an acronym that stands for External Coincidental Check. It refers to a method for proving the validity of the television usage behavior of panel participants. Under this method, the usage measured in the AGF Panel is checked against an external universe sample. The ECC is conducted concurrently with the ICC during the survey period. The latest ECC comprised more than 8,000 CATI interviews that were conducted at pre-defined measurement points on all days of the week.
