Catherine Mulbrandon's Data Scientest capabilities (per steps by Ben Fry; from

Catherine Mulbrandon took Ben Fry’s 7 steps of data the  Data Scientest steps (from his PhD dissertation (page 30 etc), dated 1997 and reiterated in his Visualizing Data book, as he describes on his website) and graphed her own ability levels in each area.

Clever use of the original ideas, along with some additional “Testing” inserts of her own. In fact, as a programmer, I would argue for testing between each of these 7 steps. I wouldn’t dare use data (from step 1) without validating it, nor move to step 3 without ensuring that step 2 hadn’t trashed the data. Indeed, each step assumes a solid foundation from the earlier steps, though, as Mr. Fry mentions, the steps are largely iterative, not linear. True, thankfully.

Turning Statistics Into Knowledge: Seminar Review and Notes

July 24th, 2009

I had the pleasure of attending the Seminar on Innovative Approaches to Turn Statistics into Knowledge, hosted by the US Census Bureau, the World Bank, and the OECD. While Robert Kosara, from UNC Charlotte, has a fairly thorough review (but not focusing on the technical aspects) of the seminar, and I would agree with most of his points (except for the presentation by David Spiegelhalter and Mike Pearson; their presentation was geared toward (and succeeded in) linking data with decision making), I didn’t read much about the technical side of things, so I thought I’d cover those areas here.

Here’s the low-down:

Mike Wirth's History of the American Flag Infographic

Mike Wirth has posted a beautiful infographic on the history of the American Flag — how it became what it is today, complete with colonies for the red and white stripes and states for each of the stars. Fantastic, and just in time for July 4th!
