Mike, I appreciate your assertion that your "research" indicates that Streaming Media West 2000 was "above average". Our own post-event customer surveys (and we have received far more than 56 of them) indicate a similar if not higher degree of success. I'm also flattered by your assumption that there were over 500 exhibiting companies, however, a brief examination of the floor plan or show guide will reveal that the number is actually closer to 290. As well, the soon-to-be published attendence figure will be at least four times your own personal estimate. This discrepency is a bit surprising, especially coming from someone who has mined every published email on streamingmedia.com and subscribed all to his own "New Media Conference Call", while also hitting every discussion list with this aleged quantitative research. As show management, we do appreciate the feedback, in fact, we rely on it. The most valuable feedback to us is that which is (1) based on accurate information, and (2) includes specific suggestions and ideas for improvement. Unfortunately, Mr. Martin's input comes up short on both accounts. Thanks again to all who are truly involved in helping us at Streaming Media, Inc. continue to build and improve this key industry event.

Spoke with 56 of over 500 EXHIBITORS. Must've been well over 3,000 attendees, on and off. Based on a person's perception (on an exhibit floor) of what precisely average is on a scale of 1-5, 2.5, in most people's mind, will be an average show. Most don't take the time to add/divide 1+2+3+4+5/5 = 3 when thinking of a fast, soundbyte response. "So is 2.5 about average?" I was asked by overtired exhibitors. "Yeah--more or less," was my answer. Mathematically imprecise, but psychologically satisfying. In any case, SMW 2000 was well above average in most people's minds.

Since 2.5 is >true average, Streaming Media West was definitely judged "above >average" by both exhibitors and attendees. This is completely statistically illiterate. Firstly, the average of a 1-5 rating is 1+2+3+4+5/5 = 3, NOT 3.5. For it to be 2.5 you'd need to use a zero to five scale. Your sample is 35 of 500, so expressing averages to 11 decimal places is not techie, it's foolish. Assuming a normal ditribution, the standard estimate of error is 1/sqrt(n) = about 17%. So your mean is 3.25 +/- 0.5. (You could calculate a proper standard deviation from your data and quote that; the point is that the difference between 3.25 and 3 is well within the margin of error) Your bins are not the same size (1-2 has 3 datapoints on, the others have 2.) In any case, binning on an arbitrary scale is not really helpful. You'd be better off giving quintiles (rank the scores in order, break them into even-sized numbers of users, and report the means of those). ============SPONSORED BY REALNETWORKS================ New RealSystem iQ - Bringing Intelligence to Internet Media Delivery Featuring the breakthrough quality of RealAudio 8 & RealVideo 8 ====> To learn more please visit: http://www.realnetworks.com/iq --- To register for Streaming Media Asia/Berlin/West/Europe/East 2001: http://www.streamingmedia.com/upcoming.asp --- You are currently subscribed to skunkworks To unsubscribe send a blank email to [EMAIL PROTECTED] To switch to digest mode, send email to: [EMAIL PROTECTED] ============SPONSORED BY REALNETWORKS================ New RealSystem iQ - Bringing Intelligence to Internet Media Delivery Featuring the breakthrough quality of RealAudio 8 & RealVideo 8 ====> To learn more please visit: http://www.realnetworks.com/iq --- To register for Streaming Media Asia/Berlin/West/Europe/East 2001: http://www.streamingmedia.com/upcoming.asp --- You are currently subscribed to skunkworks To unsubscribe send a blank email to [EMAIL PROTECTED] To switch to digest mode, send email to: [EMAIL PROTECTED] ============SPONSORED BY REALNETWORKS================ New RealSystem iQ - Bringing Intelligence to Internet Media Delivery Featuring the breakthrough quality of RealAudio 8 & RealVideo 8 ====> To learn more please visit: http://www.realnetworks.com/iq --- To register for Streaming Media Asia/Berlin/West/Europe/East 2001: http://www.streamingmedia.com/upcoming.asp --- You are currently subscribed to skunkworks To unsubscribe send a blank email to [EMAIL PROTECTED] To switch to digest mode, send email to: [EMAIL PROTECTED]
