"Making sense of the world by having fun with statistics!"
Aug 16th, 2006 by JTJ

Fascinating display of global statistics on site, Gapminder  The homepage currently has some dynamic displays related to
Human Development Trends: 2005.  Well worth watching, but be sure to scroll down the page to scan all the useful articles and presentations available.


Then, perhaps saving the best for last, go to the Gapminder Tool  at http://tools.google.com/gapminder.  Note that you can play with the axes to change (a) what is graphed and (b) how it is graphed (log or linear), and hit the play button on the bottom to see how the numbers changed over the past years.  [Thanks Patti Schank for this good tip.]


Search statistics through Google and watch it move with Gapminder

Google Subscribed Links makes it possible to search deep into Gapminder's moving graphs visualizing world development.

A most-helpful statistics site
Jun 25th, 2006 by JTJ

From the good folks at Internet Scout:

HyperStat Online [Last reviewed December 19, 1997]
http://davidmlane.com/hyperstat/

Does the mere mention of the phrase “sampling distributions” bring a tingle
to your spine? Visitors to this site will fear this basic concept of
statistics (along with many others) no longer, as it does a fine job of
explaining them in a fashion that is both lucid and jargon-free. Created and
maintained by Professor David M. Lane of Rice University, the HyperStat
Online site contains an online introductory statistics textbook, complete
with sections on normal distributions, confidence intervals, prediction, and
the logic of hypothesis testing. Each section contains a number of discrete
subsections, and users can feel free to browse around at their leisure.
Professor Lane has also included a number of external links to related
resources, including a visual statistics site by David Krus of Arizona State
University and a “Stat Primer”, authored by Bud Gerstman of San Jose State
University. Overall, this site is tremendously helpful, and will be of great
assistance to those entering the world of statistics for the first time.

Google in the 3D modeling business?
May 2nd, 2006 by JTJ

Interesting new tool from the folks at Google.  If Sketchup follows the evolutionary line of Google Maps, we can expect to see some interesting mash-ups in coming weeks.  We are looking forward to some flowchart models that can be annotated with URL and comments.  But until then….

The modeling tool SketchUp has long been a
favorite of designers, architects, and hobbyists who have used
the powerful program to render 3D images of their ideas. In
March, search-engine giant and emerging software powerhouse
Google acquired SketchUp developer @Last Software. Last week,
Google
SketchUp
was quietly released to the public. The program
has been made completely free for personal use, and it
includes tools for integrating your creations with
Google
Earth
or uploading them to Google's 3D
Warehouse
gallery.

Google is establishing a
pattern of acquiring software companies and releasing free
versions of their programs. As with Keyhole (now
Google
Earth
) and Picasa,
Google hopes to make SketchUp popular with its massive Web
audience. We get very cool free software, and Google gains new
users, loyal customers, and a potential avalanche of
third-party content added to Google Earth.


It might
appear at first that the free version of SketchUp has been
watered down, but you'll find most of its same functionality
in an easier-to-use interface. The creative possibilities are
endless, and included video tutorials will get you up and
modeling in no time. Not only can Google SketchUp create
detailed structural models, it can also be used as a more
general conceptual visualization tool for everything from
games and art projects to work flows and engineering.


Take Google SketchUp for a spin, and let us know what
you think. Then
see
what others have to say
about Google's latest software or
add
a review of your own
.

Finally, if you're a fan of
CNET
Download.com and are willing to back it up with an
Internet vote, please help support us by voting for
Download.comWebby's
People's Voice
competition. Voting ends this week.

Is your census data normal(ized) for mapping?
Mar 27th, 2006 by JTJ

Long-time IAJ friend George Dailey, ESRI's K-12 Education Program manager, contributes a fine, basic article to the current issue of ArcUser on how to normalize census data.  It's would make an especially good handout to have while teaching.

See “Normalizing Census Data Using ArcMap” at

Networks, networks, boy do we have networks
Mar 23rd, 2006 by JTJ

Comes this interesting post on the Complexity and Social Networks Blog….

Social Networks and the Business World

By Alexander Schellong

Social
Network Theory and its principles are applied by more and more
companies in a way that some of us might not be aware of yet. So what
we buy, how we rate products/services, post in forums, pictures we
upload or present of ourselves on the web is significantly influencing
other, likeminded individuals. In return we are influenced by the
network cluster we belong to for a specific habit and the like. Collaborative filtering is a key component of using social networks for different purposes. Further information can be found here. Below you will find a list of various industry and application examples:

Social Networking plattforms
There are the obvious social networking online plattforms. Among them
are the open business and personal contact manegement oriented like Tribe.net , openbc, friendster or the inivitation only communities like asmallworld.
Either planned or already implemented users can take advantage of added
services (search functionality, messaging) by paying a monthly fee
10< USD. Furthermore, there are the rather dating/partner match
making plattforms like match or eharmony.

Retail/eCommerce
Most of today's ecommerce sites use collaborative filtering to improve
sales, cross-,up- and downselling. A prominent example are Amazon's
recommendations based on various user behaviours on their website.

Music/Radio
Tapping into our musical tastes Last FM, Genielab or Pandora present us with streaming music. Here the main business model lies in linking to the respective ecommerce sites like Apple's iTunes.

Books
The same applies to the area of what we might want to read next which also serves ecommerce purposes.

Movies and more
MovieLens
is a free service provided by GroupLens Research at the University of
Minnesota. Whether, you want to book a hotel, whole vacation there are
numerous examples of collaborative filtering apps on websites.

Pictures
The most prominent example for sharing, managing and searching for pictures is Flickr or myspace. The latter gaining revenues from online-ads.

Search engines
As I have elaborated in an earlier entry on google bombs the network structure (ties) play an important role in search engine algorithms.

Knowledge Base and OpenSource
The online encyclopedia Wikipedia builds on the power of decentralized, voluntary collaboration building an enourmous depository of multi-language information. Whether it was the development of Linux, Mozilla/Firefox or MySQL all rely on and consist of social networks. Further examples of openSource projects can be found at Sourceforge.

SNA Consulting
As we can see the character and concepts of networks is mainly utilized
for recommendations. Actual applications of SNA is done by a few
companies and consultants like Rob Cross, IBM, Orgnet or Visiblepath.
These companies try to uncover the informal networks within
organisations to improve knowledge sharing, initiate change or bridging
silos.

Finally, you can always follow latest trends in social network analysis at PNG's subpage on SNA by Ines Mergel.




Show us the money!
Mar 11th, 2006 by JTJ

The Canadian Cartographic Association today points us to another interesting application of data collecting, analysis and charting.  See: http://ccablog.blogspot.com/2006/03/index-of-economic-freedom.html

Index of Economic Freedom

Published Friday, March 10, 2006 by CCAer | E-mail this post  



The
Index of Economic Freedom has been published every year for the past 12
years. It assesses each country’s economic freedom by evaluating a
country’s performance on a number of factors, including trade policy,
fiscal burden, government intervention, monetary policy and property
rights, among others. Using the latest results (
available in Excel format), the index creators have also put together a map of the world (also in pdf format) that provides a quick overview of economic freedom throughout the world. Also interesting to view is a chart showing the correlation of per capita income and economic freedom. Individual country reports / analysis are also available.


The complete report, along with the methodology and process used, is available for download.


Measuring and visualizing words
Feb 3rd, 2006 by JTJ

In recent weeks a sub-set of journalists have begun working with the problem of how do we  quantify and illustrate speech.  Or speeches.  The Cyberjournalist.net newsletter (at the American Press Institute) reports:

latimes.com's Eric Ulken built keyword clouds
comparing the text of President Bush's first State of the Union address
— delivered less than five months after the terrorist attacks of Sept.
11, 2001 — with Tuesday's 50-minute speech.

They list commonly-occurring words in the speeches, giving greater
visual weight to those that appear more often. Arranged side-by-side,
they show some interesting contrasts (and similarities).”

Sorta interesting, when it's working.  We applaude the attempt as a fine beginning, but what's missing is some context and explanation, the “So what?” factor.  In fairness, the site's author recognizes the shortcoming, saying: “Of course, they lack any kind of context, but who needs that? (We're kidding.)

On the other coast, ever-inventive Matt Ericson takes another bite of the State of the Union apple and offers up a more interesting visual, “The Words That Were Used.”  [Look in the left column for link to graphic.  But the toned “bubbles” actually show up better in print than online, so if you can't see it well online, try this (and may the copyright gods forgive us).





Charlotte Mortgage Foreclosures
Jan 21st, 2006 by JTJ

Three-Day Series

http://www.charlotte.com/mld/charlotte/news/special_packages/foreclosure/

summary stolen from (http://www.thescoop.org/)

Charlotte Mortgage Foreclosures
Posted by Derek on January 18th, 2006. Filed under Fed Data, Mapping.

     Lisa Hammersly Munn, Binyamin Appelbaum and Ted Mellnik of the
Charlotte Observer have a three-part series on mortgage foreclosures,
finding that home loan failures have more than quadrupled in Mecklenburg
County since 1999. More foreclosures are filed here, per person, than any
other county in the state. On average, 11 Mecklenburg houses are sold in
foreclosure auctions every business day. The owners are evicted, their
credit ruined, and they face thousands in court fees and moving expenses.
     Included with the series is an interactive map of Mecklenburg County
foreclosures and a sidebar reporting that local loans from the Federal
Housing Administration are failing at almost twice the national rate.



So is there a story in the song(s)?
Jan 14th, 2006 by JTJ

From Complexity Digest:

Semantic Descriptors To Help The Hunt For Music, ( Innovations-report)

Excerpts: You like a certain song and want to hear other
tracks like it, but don't know how to find them? Ending the
needle-in-a-haystack problem of searching for music on the Internet or
even in your own hard drive is a new audio-based music information
retrieval system. Currently under development by the SIMAC project, it
is a major leap forward in the application of semantics to audio
content, allowing songs to be described not just by artist, title and
genre but by their actual musical properties such as rhythm, timbre,
harmony, structure and instrumentation. This allows comparisons between
songs to be made (…).


Source: Semantic Descriptors To Help



Should
this come to fruition, might there be stories in patterns — regional
patterns — in music?  How could we map this?  And when?





Tilling the soil makes for fertile crops, Congressionally speaking.
Dec 5th, 2005 by Tom Johnson

Kudos to Derek Willis and Adrian Holovaty of The Washington Post for the Washingtonpost.com site “U.S. Congress Votes Database.”  One element we find of recent and special interest is the “late night votes
variables for both the House and Senate.  With a little more
probing and data slicing and dicing, it would make an interesting bit
of visual
statistics/infographics to do a longitudinal comparison of the time of
votes in various congresses.





This site/searchable database is a fine example of how investing in some basic data preparation
can create the potential for a ton of stories.  Why, for example, do
Democrats have such a preponderance (18 out of 20) of Representatives on the “missed
votes
” list, but only 9 out of 20 on the similar list for the Senate?




This is
also a fine example of how a newspaper can do good things for itself
while doing good things for the community and readers.  This
database gives the WP reporters and editors a quick look-up of
Congressional activity, the kind of fact and detail that can enrich a
story.  At the same time, citizens can turn to this value-added
form of the public record to answer their own questions.




Derek Willis wrote to the news librarians listserv:



“Folks,



It's not part of a story or series, but the Post today launched a site

that may prove useful to your newsrooms or even as an inspiration to

learn Python: a congressional votes database that covers the

102nd-109th congresses (1991-present). Currently browsable, we're

working on adding a search engine and other features to it. Adrian

Holovaty, who works for washingtonpost.com, and I assembled the data

and he built the web framework to display it. All of the data is

gathered using Python, the database backend is PostgreSQL and the web

framework is Django.”
