They worked up until a couple of days ago, I imagine it is due to a problem with the renewal of the domain thunderbirdsix.org (as I store the lecturecasts there). It will probably be fixed by tomorrow.
At NYU I took a full semester course in polling and oy. Statistical misinterpretation is only the first problem with the pundits’ analyses. How were the questions phrased? How was the sample chosen? How was the data collected? Exit polls are pretty accurate because many variables are just eliminated, but as for the rest of them….Depends.
And data is plural–but Data is singular. (Heh, heh.)
Oh yeah, how are questions asked is key. The class in the lecture theatre just before me is a course on psychmetrics, they deal with that extensively.
I gave up on telling people the plural is data and the singular is datum, as frankly it has gotten to the point that nobody seems to care 🙂 Believe me, I did for years.
FYI–the last three lectures won’t download via iTunes…!

Re: The importance of statistics: The cover story in last Sunday’s New York Times Magazine was about the difficulties (statistical and otherwise) with epidemiological studies ( http://www.nytimes.com/2007/09/16/magazine/16epidemiology-t.html?_r=1&ref=magazine&oref=slogin ).
