[2b2k] Census Bureau ends Statistical Abstract

David Weinberger

The Census Bureau is no longer going to fund the creation of the Statistical Abstract of the United States, apparently in order to save $3M a year.

Stephen Downes: Half an Hour

Technorati right now offers no statistical validity and should not be quoted as indicative of web trends or blogosphere trends.

Andy McAfee

As he wrote, “Given the advances in baseball statistics, one might hope it would be possible to deploy modern analytical tools to adjust today’s chemically enhanced stats and put them on a level playing field with those of yesteryear. More specifically, we’d expect to see increases in the standard deviation (a measure of spread) of all hitters’ batting averages, all pitchers’ walks+hits per inning pitched (WHIP), and other such statistics.

A series of emails and skype calls today built up a head of frustration with some people's obsession with statistics and data. Another with a colleague frustrated by people talking about the validity of statistical patterns for low volume datasets and not realising that simple visualisation can enable an intelligent person who make sufficient sense to act. Humans can change the context through intent (or accidentally) which can render any statistics out of date/data/meaning.
