## What Do I Do With All This Data?

I have a research project involving about ~90 subjects in two (self-selected) groups. I have collected a number of variables about these subjects (from public sources), and now I would like to do some statistical tests to say whether these variables are significantly correlated with membership in one group or the other. How do I do this? I have a basic knowledge of R and access to Stata 14. [more inside]

## And then the kangaroo said, "did you bring the vitamins?"

Years ago my college roommate took a statistics course. In the textbook was a small, confounding cartoon that appeared to make no sense but was hilarious in its absurdity. I would like to know about that cartoon. [more inside]

## Help me not screw up teaching my students about p-values

I am a TA in an introductory college biology lab. Soon, I have to teach a class of mostly freshmen about t-tests and p-values in conjunction with a field experiment that they are conducting and on which they will have to write a report. I want to make sure I do this rightâ€”help me! [more inside]

## OkCupid Blog RIP...

## Fallacies and Errors in Inferential Statistics

I have recently been introduced to the concept of pseudoreplication as a mistake that people often make when using inferential statistics to evaluate treatment outcomes. My field (evolutionary and conservation biology) makes heavy use of inferential statistics, including techniques that are vulnerable to pseudoreplication, yet nowhere in my formal education have I been taught about how poor experimental design and lack of statistical rigor can lead to fallacies like this. My personal statistical proficiency is poor, but I am working to remedy that. To that end, could folks help me by identifying and ideally explaining whatever other potential pitfalls you can think of, and explaining how they can be avoided through careful experimental design and data-analysis?

## Educate me on these crime statistics

The Wikipedia page on statistics about rape shows a very high crime rate for countries like UK, US and Australia in stark contrast to, say, India. The gap can't be explained simply by under-reporting, as that exists in all these countries (even assuming different rates of under-reporting). Is it because these countries have different definitions of rape? Or something else? [more inside]

## Unexplained increase in Flickr visitors

My Flickr account is totally not popular, and for good reason. It's mostly just a bunch of photos for my parents to look at and I average about 1 visit per day at best..

## Help me find a web site that I should have signed up for years ago.

[Find-that-website] So. There's this website where you would enter everything you do everyday - what you had for breakfast, what color shirt you wore, what TV shows you watched, whatever. After you had compiled enough data, it would come up with dubious statistics relating things you have done against world news and other users. For example, I might find out that every time I have eggs for breakfast there's an earthquake in SF, or that some guy in California wears a purple shirt every time I forget to floss. I might have found this on the blue or in PC World, and it was probably sometime around 2006. I've been looking for this site forever. Help.
