Dear 43 Things Users,

10 years after introducing 43 Things to the world, we have decided we have met our last goal: completing the incredible experience that has been 43 Things. Please join us in giving one last cheer to all the folks who have shared their goals with the world, as well as all the people who have worked at The Robot Co-op to build this incredible website. We won a Webby Award, published a book, and brought happiness to a lot of people.

Starting today, 43 Things users can export their goals and entries from the site. Starting August 15, we will make the site “read only”. 43 Things users will still be able to view the site and export their content, but we won’t be taking any new content from users. We hope to leave the site up for folks to see and download their content until the end of the year. Ending on New Year’s Eve takes us full circle.

It has been a long ride (one of our original goals was to "build a company that lasts at least 2 years” - we beat that one!) While we wish the site could live on, it has suffered from a number of challenges - changes in how people use the site, the advertising industry, and how search engines view the site. We wish the outcome was different – but we’ve always been realistic about when our goals are met and when they aren't.

As of today, you will be able to download your goals and entries. See more about that on the FAQ page. Thanks for 10 great years of goal-setting and achieving.

- The Robots.

I got my Statistics book today

And started reading through the first chapter. Ouch. The math is harder than the concepts – but I’m pushing on. I’m going to make an ass of myself by doing teach-ins to the other Robots (one of whom is a Maths major).

Tomorrow I’m going to be outlining an idea for using “capture/recapture” for measuring repeat visitors to 43 Things to the rest of the Robots. This is a good real world application of sampling and probability – but it raises funny issues like “why not just count the repeat visiors”. Sampling makes the data size much more manageable and seems like it would allow for things like measuring the repeat and defect rate by “vintage” (when the sample was taken).

Let's get this started
What are the fundamental concepts one should understand? Here’s a crack at a list I gleamed from this book:
  1. axioms and theorems of probability
  2. random variables and probability distributions
  3. mathematical expectations
  4. special distributions (binomial, poisson, normal)
  5. sampling theory
  6. estimation theory
  7. tests of hypothesis and significance
  8. curve fitting, regression, and coorelation
  9. analysis of variance
  10. non parametric tests

What do you think? Is this a good list to start from? I’m thinking of buying the book and moving through chapter by chapter. I know most of this material at some level, but I’ve been thinking I want to give a short presentation on each section as “proof” I know it. Look out co-workers! You might not have known you’d accomplish this goal as well.
