TOTAL ITEMS- 2000
ITEMS WITH BIDS- 297
TOTAL- 14.9%
The estimated overall sell-thru rate for dollar items is 6.5%-7.5%, and the total site sell-thru rate is 1.5%-2.0%

I don't really want to question your creditability, but these numbers are drastically different from those posted by the site. Bidville shows that over 10,000 items have been posted for the sale and over 2000 have been sold or have bids. Also how do the number of items with bids decrease while the number of bids is exactly the same?

Not to mention those posted by El Supremo Bean Counter at the Moo.
I prefer those posted here

stavecards the bid rate is taken from the first 2000 open items available on the lackluster search feature. As of this morning 249 of the first 2000 items had bids. Using this number I can estimate the overall bidrate of open items at 6.5%-7.5%, with a total sale thru number of 12.5%-13.5%. I think my numbers are for the most part on target.

Rather than use a poor sampling method, why don't you use numbers that are readily available for all of the items listed?
For those interested in accurate statistics, the following numbers were posted by the site today.
Total Items: 14,463
Total with Bids: 2,915
Overall Sell-Rate: 20%
Anybody that has taken a basic statistics course would not consider your numbers very accurate.

Stave the interesting thing about stats is if 10 people do them, you will have 10 diffrent numbers. Will we ever have the exact rate? No, because the search engine at bidville can only pull the first 2000 items in ending order. Do I believe the sell-thru was 20%? No, because the bidrate never made it that high. Nobody will ever agree on the stats, but I find it enjoyable.

Blairwitch,
Even Dimview is not disputing the stats from the sale posted by Bidville. The one big area that you are overlooking are auctions that close with a BIN. Anymore on sites that have the BIN feature, a large number of auctions close in this manner. Therefore those would not show up when you look for active listings.
You don't have to bother with sampling when someone has access to all of the listings. But I guess when you don't want to accept the truth, you will go to any extent to start a different story.

I guess dimview was right.
There's always "controversy" when folks are either unwilling or unable to understand the methodology used in making estimates like this.

Oh, I understand your methodology. Don't understand the need for sampling when statistics on the entire population is available. Also since your method of choosing your sample does not insure a representative sample (lack of random selection), your results are not statistically valid. I don't really care whether the numbers are good or bad. My request is for accuracy and validity.
