## So, um, how big is your....kneecap?

Say I'm an industrial designer (I'm not), and I have to design a car seat, desk chair, climbing harness, body armor, or some other piece of equipment that has to be able to interact with a whole bunch of differently-shaped humans on a regular basis. What resource do I use to find out things like average foot width, or average knee circumference, average jaw length, or any other specific anatomical measurements? [more inside]

## It's hard to Google infographics

## Data on civilian casualties of war?

I am interested in seeing some comparative data on the civilian casualties of warfare, particularly in the 20th and 21st centuries. Are there any great analyses of this topic, perhaps on DVD, YouTube, or illustrated in books with graphs? (I have a hard time envisioning the magnitude of these things when they are presented only as bald numbers.) I started thinking about this topic after watching The Fog of War, which is a documentary about Robert McNamara. He presented some amazing comparative information about World War II and the Cold War. I would love to acquire a similar critical context for other conflicts, including the recent wars in Iraq and Afghanistan.

## People who do x are more likely to y

I'd like to read about unexpected statistical correlations that begin to emerge when companies or academics use data mining to analyze behaviour in large groups of people. I'm looking for articles/sites that are a little more serious than this (found while searching Metafilter for this topic). More like this (NYT: Target is able to predict that some customers are pregnant before their children are born). Thanks for your recommendations! [more inside]

## Bathrooms and Statistics

My workplace has 3 small bathrooms. It seems to me that if I go to use one of them, and it's occupied, there is a statically higher chance the 2nd and even 3rd bathroom will be occupied (vs the chance that they would be occupied if the 1st one was not). Is it true? [more inside]

How? [more inside]

## Calculating a binomial distribution confidence interval for a particular experiment

[StatisticsFilter] I’m trying to understand the extent that the statics of a particular experiment can be evaluated and trying to relate that to a 95% confidence interval. The experiment is considered “a standard”, but I want to keep the discussion as “high level” as I can so that we focus on only the relevant details. Any help or pointers in the right direction are greatly appreciated. [more inside]

I have a research project in mind. It involves the use of statistics. I am a typical humanities grad with no real background in the quantitative social sciences, and need some guidance.

## That's not a blue moon; pull over...

Can anyone point me to actual data on how often motorists receive traffic tickets? I'm looking for where the top of the bell curve is, so to speak - obviously, individuals vary widely, which is kind of the point of my question - how often does the "median" driver receive traffic tickets?

## Envisioning a syllabus on the Display of Quantitative Information

I am planning on teaching a course on data visualization to some Ph.D. students in the social sciences, and could use some ideas about designing the syllabus.

## Will fit statistical models for food (and additional money for rent and whatnot)

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]

## Help me make sense of the facebook

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]

## Creating my own crime map

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.

Does such data even exist?
I'm only asking out of curiosity, not for any professional or education project.

## A little help on a statistics paper on inflation, in German.

I am looking for a little translation help on an inflation statistics paper in German language (look in more inside for the link).
