I've been focusing on getting a tenure-track academic position for a long time, but I feel like it's foolish not to be looking elsewhere for work, too. What jobs might I be a (reasonably) good applicant for? (relevant personal details below the fold) [more inside]

I'm in charge of inviting people to Facebook events for a small nonprofit. We've started tracking the number of people that say they are going and maybe going on Facebook vs. the number of people who actually show up to the event. It looks like of the people that say they are going or maybe going to an event about 50% actually show up.
Is this a normal show up rate? Has anyone done statistical study on this kind of data? [more inside]

I want to create a "crime map" of a city over time. I know the dates of the crimes, and I know the physical address. I'd like for the crime map to be something that I could show a crowd in a presentation such that the audience members could witness for themselves how a particular part of the city changed as time went on. I was thinking of Gapminder
as the ideal, but spatially and dynamic instead of simply numbers. I suppose it'd be possible to get something up and going with GIS, but I was wanting to do it in a way that was idiot-proof as this is only valuable to me if I can do it easily without a ton of time learning some new program.

How can I locate sources for statistics on the outcomes of Canadian criminal court cases, that include such data as type of defence counsel (ie Legal Aid, from large firm, high profile, new in field, or preferably cost of counsel), amount of time before trial, income/profession of defendant, sentence given, and sentence actually carried out?
Does such data even exist?
I'm only asking out of curiosity, not for any professional or education project.

I am looking for a little translation help on an inflation statistics paper in German language (look in more inside for the link). This official paper is quite interesting for students of statistics and social students interested in perceived cost of living vs actual cost of living, in Europe as well as in any other country, as it allegedly shows that indeed there were some excessive rouding of prices during the conversion to euro in Germany.

The presence of A is a good sign B exists, but as people learn about the A trick they take pains to display it so it isn't as reliable a sign of B anymore. What's the term for this, is its rate of adoption reliably based on other variables, and who writes about it? [more inside]

What sort of survey are my colleagues planning? It would involve questionnaires dropped off at a variety of businesses (tour agencies and hotels, mostly), aimed at capturing details about their clients. This doesn't seem to fit the examples I see discussed in online resources on survey methods. To top it off, both the time frame and budget are limited. Where can I find best practices for this sort of survey--and how can I determine which best practices should be given highest priority? [more inside]

I'm currently performing a mock research comparative analysis for a class. I'm researching the financials of 'our' metrics versus our highest competitors. One of the questions I'm attempting to answer asks if the variances (or standard deviations) of 'our' profit margins are statistically similar to the variances in profit margins of our competitors over a five year period. I have 11 companies representing the profit margins of our competitors, and of course the reports on our profit margins for these five years.
Now it's been a while since my last stats course... so I'm wondering, would I use an F or Levene's Test to answer this? Or am I completely off base... and should look to another form of analysis.

I'm trying to find the number of food products that are sold in the U.S. that contain high fructose corn syrup. I've done some preliminary searches and have found some lists, but I've come up dry when trying to find actual numbers. I'd like a reliable source that I can cite, but I'll take almost anything at this point. I am at a university and have access to a large number of subscription database resources, so I'll keep looking. But I thought metafilter might be able to help out here.

How can I test if one predictor variable in a regression is significantly better than another predictor variable?
i.e. If I regress X against A I get an r^2 of .99 and when I regress X against B I get .98. I need a test to see whether this difference is statistically significant. [more inside]

How do TV channels figure out how many people watched a particular episode (e.g. XX million watched American Idol)?
I often hear things like XX million viewers watched American Idol or some other show.
How do the news guys / broadcasters come up with these numbers??
Surely they are not able to track what is being watched in peoples homes.
So I guess this is some kind of math or projection. Any idea how this is done?

In his TED talk
, Sean Carroll very briefly discusses Feynman's explanation about how the universe we can see and experience is not a statistically lucky perturbation, before moving on to the rest of his lecture. In other words, Feynman seems to discount the "Boltzmann brain
" hypothesis, that we're not just the ephemeral product of a lucky shuffle of a metaphorical box full of marbles. Can someone explain this to me in words other than Carroll's, i.e., what evidence Feynman was using to prove his argument?
