Sujet: Re:The ratings are clear and precise.

Artful Dodger: Sorry Dan, but from what I've read about the system of collecting data in the USA regarding viewers.. it's a little vague.

Only 5000 TV sets in the USA are used to calculate the viewing statistics for the whole country, the system also can count a program as being watched even if it is only watched for ten minutes or less. It can also count two programs watched within an hour period as being watched based on that 'ten minute slot'.

It is calculated that there are 99,000,000 households in the US that have TV sets, going back to my days of studying statistics in college I feel the sample of only 5000 viewers too small to be " clear and precise".

Also, It seems from looking at the system of knowing who is watching is dependant on pressing a button, which is acknowledge as not being always done by the data collectors.

... Call me fickle, but to me this is not good realiable statistics. It may be good enough to calculate how much to charge for advertising, but overall I would not call the data collection system accurate or "clear and precise".
