I have just completed my MSc in mathematics in Europe. I do enjoy math, but I spent my uni years feeling like a autodidact hippie marooned on an island full of Mr and Mrs I-Want-A-Good-Job. My main interests revolve around humanities (literature/history/anthropology) and economics (but not finance), and instead of starting a "stable" well-paying career I dream about something inter-disciplinary. I am very open to earning little money and relocating just to do kind of work that engages those skills. What are some random uses of my degree? [more inside]

Does anyone know if there is a trial version of SPSS to download for a Mac? I tried downloading a free trial, but I didn't trust the website that I was on. Are there add-ons for excel that would allow me to do this? Any suggestions are welcome.

I play fantasy baseball in a league with friends, some of whom pay no attention and others who have baseball stats in their very DNA. I myself am moderately ok most of the time, but generally have a low-level understanding of what I'm doing, so when things go wrong my solution is usually to flail around with free agent players while watching my ship sink, week by week. I'd like to get off this plateau and actually learn more about the game, sabermetrics, etc so I can be a legit contender, but I'm lost in the morass: every resource I can find is super basic or way over my head. Help! [more inside]

I'm looking for a social science type book, probably an edited volume, that tackles an issue using lots of data & statistical tests / arguments to debate an issue. I am less concerned with the issue being debated, and more concerned with learning 1) what constitutes proper manipulation of data 2) what tests are appropriate and when 3) what proper inference is. I'm not afraid of math.

There's a well-known joke about statisticians. "Did you hear the one one about the statistician who drowned trying to wade across the river? He knew it was three feet deep...on average." I've searched for a source for this joke on the internet, but haven't found one. Does anyone have any idea where this joke originated? Call me an academic, but I feel the need to attribute it if I can.

Are there any free resources that provide sports statistics with more than simple averages? [more inside]

I'm looking to take an intro to statistics class this fall or summer. I'd be up for taking it online or in person, if in person it would have to be in or near Washington DC. It could either be an undergraduate or graduate class, but not one where you have to know calculus. Has anyone taken a good introduction to statistics class in the DC area or online that they could recommend?

I have 600 images tagged with keywords. In addition to nice pictures of tag clouds and frequency calculations, what sort of smart, insightful analysis can I do with these data that could reveal relationships between the tags and other (more formal) data attached to the images? Any advice on software tools (Windows, preferably FOSS) would be appreciated. I have some training in statistics and I have actually done textual statistics before but only briefly so I'm not familiar with the current tools and methods.

I'm currently enrolled in a PhD program for statistics and operations research, and in two more years I can grab that PhD. Alternatively, I can jump ship now with a MS, headed for the (inviting/inevitable) waters of industry.
Knowing that I have no interest in staying in academia, give me some motivation to finish. Or, tell me to quit because actual work experience is more valuable! What roles should I be looking at other than Data Scientist? Would it be feasible to get a position doing private research, and would that be awesome? Bonus points if you can tell me what skills I should be cultivating to be hire-able (software engineering)?
P.S. I will also do some more chatting with profs and former students to figure out how I should be directing myself, but I hope the HiveMind can provide some complementary ideas.

An NPR blog
cites an NSF study which claims that 26 percent of Americans asked answered that the Sun goes around the Earth, rather than vice versa. Believing that 1 in 4 of my fellow citizens doesn't know that the Earth circles the Sun is hard enough. But thinking about that number, it seems worse than that: if 26% got a 50/50 question wrong, wouldn't another 26% have answered correctly just based on chance rather than knowledge? That would mean that roughly half of Americans didn't know (and then split evenly on their guess). The idea that half of Americans don't know seems intuitively ludicrous to me. Am I missing something in how I think about this? Please help my statistically challenged brain... [more inside]

There's a lot of statistics online about how many children are sexually abused, but not much about how many adults are doing the abusing. I did read one article that mentioned in passing that about 1 in 20 men and 1 in 3300 women have sexually abused a child, but I think that was referring to only prepubescent children, not minors in general. The article was pretty old too, and there was no source for where they got that information. If anyone knows where I can find a reliable statistic regarding the percent of adults that sexually abuse children then I would appreciate it. [more inside]

If I'm going to succeed in a field I am considering (bioinformatics), I'm going to need to learn a good deal of statistics. I have limited experience in the subject and have never found the details of it especially compelling. Can you recommend some books on statiistics (not necessarily light on the details) that are well written and interesting? Something designed to get the layman interested in the details could be good, but textbook recommendations would also be good.

I post a lot of URLs to social media sites (and since one of those is Twitter I often use url shorteners) that point to my own publishing company's website, and also directly to where I sell my books on Amazon, Barnes & Noble, etc. I know services like ow.ly will track how many clickthroughs a url will get, and I think they can give me multiple shortened urls for the same target url. I'm wondering if any url shortening sites will also let me keep track of all of my shortened urls and give them nicknames or make notes (so I can note where I've used them) and give me a chart or spreadsheet or something that shows me which urls are getting the most traffic. Or if there's an app or separate website where I can enter the info that will then collect the tracking data. I'm trying to avoid having to manually check every url's visitors data.

My office has recently had some funds open up and we are looking into investing in some statistical software to make our lives easier. We do a lot of work with distribution fitting, Monte Carlo analysis, and regression analysis with data sets that may contain left or right censored data. Unfortunately, we only have a few days to identify the best software package for our buck. Alternatively, the idea has been floated to download the free R software and spend the money on some training to get over the steep learning curve. What program or approach would be the best use of our money?

The final value of "test statistic t" falls in the rejection region for 95% confidence interval, but falls in the nonrejection region for 99% confidence interval.
Should I perform additional calculations before rejecting my null hypothesis?

So I'm beginning a statistics PhD program this fall and I'm concerned that my math skills have gotten rusty since I haven't done anything related for the past two years. I've been working as an actuary since I graduated college but I don't do that much math--mostly a lot of programming. Has anybody been in a similar situation to me? How was the adjustment for you? I'm considering retaking advanced calculus and linear algebra during my first year (probably next summer before I take 2nd year advanced courses) just to refresh myself again.
