## Quick Data Collection Problem

I have a CSV with one column that contains User IDs. I need to make another CSV that counts how many times each User ID appears in the document, and output it to another CSV That has something like UID1 >> 3; UID4 >> 1; UID20 >> 0. There are thousands of User IDs, so I need to be able to set up a range for it to scan for. Is this possible with free software and not much programming expertise? [more inside]

## 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]

## Cubicle Denizen Dilemma: the name for an “average” if the data are weird

Our company has decided to measure the jobs we do by assigning points to tasks. The problem here is that departments don’t do the same thing, or the same amount of things. What concerns me is that the company wants to publish a company-wide average, against which members in each department will be compared. [more inside]

## Career Development Suggestions for making sense of and displaying data

I currently work for a growing company doing various social media marketing for small businesses. I have been finding that I receive a lot of satisfaction doing activities related to what I learned in library school. I enjoy collecting, organizing, and providing data and information for our internal staff and making things approachable. One weakness I see is that we are especially data rich and insight poor with social media. I would like to know if there are any recommended programs for data mining or statistical analysis?

## Scaling issue calculating similarity between paired numbers

I have a list of paired numbers that span multiple orders of magnitude, and I need to find a method to a) compare within each pair in a way that does not disproportionately bias the comparison at the high or low end of the list, and b) define which pairs are dissimilar enough to be excluded from further analysis. The dataset itself follows a rough sigmoid curve, with a few pairs in the 1000s, more in the 100s, a lot in the upper 10's, some in the low 10's, and a few in the single digits. I have tried a few different comparison methods so far, including percent difference and relative percent difference of both the raw and log-transformed data. [more inside]

## How do I elegantly present tabular, statistical data online?

How do I elegantly present tabular, statistical data online and automatically?
I'd love some examples of beautifully presented tabular data online - something that works natively in a browser, ideally also on a tablet and mobile as well. Some interactivity (sorting, filtering) also OK but priority is usability and elegance like you'd find in printed statistical abstracts. Bonus points for open source web tools / frameworks that could help automate this from a database! [more inside]

## Something something quantified self something something

Hello MeFites. Lately, I've become interested in the idea of "Quantified Self", essentially, self tracking. A diary of daily events, such as when I woke up, how much coffee I've had, my productivity level and so forth. I'd like to collect some of this data to see if I can deduce some patterns. Maybe when I drink coffee, I go to bed later, and I'm not as productive for example. To achieve this, I think I need a piece of software. [more inside]

## Seeking advice/help about statistical tests of significance.

I have a wonderfully large dataset that I'm working with for a long-term project. I am analyzing a small section the dataset for my masters thesis. In meeting with my thesis advisor last week, she suggested I run some statistical tests of significance on the 4 tables I'm working with. She knows that I am yet to be versed in quantitative analysis methods (I've done solely qualitative work thus far) and that I'm under a massive time crunch to get this done. She suggested I seek help from others, as she doesn't want me to get bogged down with figuring out this step, and would rather I concentrate on analyzing the other aspects of this data. To this end, I'm wondering if somebody might be able to suggest the best type of test of significance to run, the easiest way to run it, and a good, simple resource for what the resultant values mean?

## How does the CDC measure the spread of H1N1?

There's no special place to turn up if you think you've got the swine flu to be tested or otherwise counted--hospitals and clinics tell people to just stay home unless they are having actual health complications. How is the CDC able to say that 22 million people have been infected with H1N1 when if you don't have to be hospitalized, nobody will even test you for it?
