I'd like to estimate the number of days a year when the high temperature is likely to be below a particular threshold, e.g. below freezing. This turns out to be harder than expected.

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!

I'm looking for data to use in a statistics class. The data set needs to have less than 25 variables and at least 200 individual records. Any fun/unique/silly ideas? I need to right a paper analyzing this data -I'd like it to be interesting. I need access to raw data - it is okay if it has already been analyzed but I need to show that I can analyze it.

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.

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?

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?

A statistics / scientific convention question. I've noticed in scientific journals that often when a set of data is presented with values normalized to one of the sample groups, and the value for that sample group is arbitrarily set to 1, 10, 100 or whatever, to simplify interpretation, the variability/error data for that one sample group is left out. Is there a good statistical reason for that or is it just some random convention with no good reason?

I'm working on a data graphic with a linear scale horizontally but a logarithmic scale vertically. The y-axis (count scale) values range from 0 to 200, with the mode average in the lower third of that range. I'd like the graph to take up only a third of the size vertically that it currently does.
I can recognize a logarithmic plot when I see one, and I know what I want generally, but I don't have enough of a handle on the Math to actually calculate and plot such a scale myself... at least accurately.
I'd appreciate any help in understanding the Math. It's one thing to see a formula, and another to know how to use it. I'm also not 100% sure that this is the best way to handle such a graph, so alternate strategies or confirmation are welcome.
