The margin of error is the way that statisticians provide detailed information about the uncertainty associated with a particular estimate from a sample to a population. A key point that is misinterpreted all over the place is the fact that the margin of error reported in the media is generally the amount that should be added or subtracted from BOTH candidates estimated percentages in order to report the uncertainty!

A nice explanation is in this pamphlet on polling from the American Statistical Society: http://www.amstat.org/sections/srms/pamphlet.pdf

“A misleading feature of most current media stories on political polls is that they report the margin of error associated with the proportion favoring one candidate, not the margin of error of the lead of one candidate over another. To illustrate the problem, suppose one poll finds that Mr. Jones has 45 percent support, Ms. Smith has 41 percent support, 14 percent are undecided, and there is a 3 percent margin of error for each category.
If we note that Mr. Jones might have anywhere from 42 percent to 48 percent support in the voting population and Ms. Smith might have anywhere from 38 percent to 44 percent support, then it would not be terribly surprising for another poll to report anything from a 10-point lead for Mr. Jones (such as 48 percent to 38 percent) to a 2-point lead for Ms. Smith (such as 44 percent to 42 percent).”

Finally, the Digital Entrepreneurship social community (http://ritdigient.ning.com) created by my class and I has begun to attract outside interest. Entrepreneur Jamy Nigri has been a valuable addition, offering great insights to the community. It is this last which stands to be our lasting representation in this area, so I continue to bring people and contributors to this site. Tomorrow, I will see if I can get Jeff Bezos or others to join.
My only regret? That I did not make it public to begin with. Now I have to wait for Ning to allow switching private to public.

I burned the Edgy-Eft distribution to a CD a plugged it in. Lo and behold-BLACK SCREEN. I knew what had happened too-as soon as it switched to X windows, the monitor would not sync. Admittedly, my hardware was a little long in the tooth, but I had higher hopes.

So, I began my typical Linux experience of browsing for the fix to my problem. I found a very active group of people debugging a similar issue.
I began trying all of their suggestions. This involved many trials, failures, and reboots with no success. I even burned a copy of the non-released Feisty distribution, but with no success.
This morning, I ran across a very simple set of instructions, which reminded me that I rather than trying to patch the OS, I should just try to reconfigure what was there. I ran dpkg-reconfigure xserver-xorg and told it what kind of video card I had, and voila-<full on Ubuntu.

I am writing this post from Firefox on Ubuntu now. I like the font rendering and the ability to multitask better than Windows XP. I already connected to the shared printer and printed with no problem. It appears that Linux may have reached a critical state where it can give MacOS or Windows a run. I’ll let you know.

So naturally I think this would be good for me too! The first five people who comment on a post on this blog can meet with Dr. Perotti in his office at RIT. Woo-hoo! Good luck to all and as Ashley would say: Have Fun and Peace Out!
