Corrie ratings for last Monday - how can they be so accurate?
I guess this is more of a technical question, but how can they be so confident with their figures? In this article they even claim a precise figure for viewers who tuned in during the last few minutes. 59.28%? How is this possible? Surely extrapolating from their relatively small (?) sample can't provide such accuracy ... Just curious

the TV stations use a system of viewing diaries,much like listening diaries in radio.a supposedly representative sample of the public is asked to fill out each programme they watch and the figures are then extrapolated from the available data.

Every household which is represented has a little black box fitted to their t.v's and this does the legwork. It will record all the data, and sends it back to the BARB HQ nightly. That's how you get accurate records. BARB |

THANX.i didn't realise TV had gone down the electronic measuring route similar to RAJAR for measuring radio audiences.
