Gallery of Data Visualization
Mar 25th, 2005 by JTJ


This Gallery of Data Visualization displays some examples of the
Best and Worst of Statistical
Graphics
, with the view that the contrast may be useful,
inform current practice, and provide some pointers to both historical and current work.
We go from what is arguably
the best statistical graphic ever drawn,
to the current record-holder for the worst.

Monte Carlo Simulation in Excel: A Practical Guide
Mar 25th, 2005 by JTJ


There are many things that faster computers have made possible in recent years.
For [journalists], scientists, engineers, statisticians, managers, investors, and others,
computers have made it possible to create
models that simulate reality and aid in
making predictions. One of the methods for simulating real systems is the ability to take
into account randomness by investigating hundreds of thousands of different scenarios.
The results are then compiled and used to
make decisions. This is what Monte Carlo
simulation is about.


      Monte Carlo simulation is often used in business for risk and decision analysis, to help make decisions
given uncertainties in market trends, fluctuations, and other uncertain factors…..


     
This article will guide you through the process of performing a Monte Carlo simulation using
Microsoft Excel. Although Excel will not always be the best place to run a scientific
simulation, the basics are easily explained with just a few simple examples.”

GovTrack.us — Good "alert" tool
Mar 22nd, 2005 by JTJ

GovTrack.us
is a free, publicly available, privately run, open-government-advocating web
service in good company with such sites as Project Vote Smart and

then hit the big time with mentions in
BusinessWeek

and the
New
York Times
(registration required). The attention-getting feature is this:
GovTrack will send you a notice via email or
RSS feed when official legislative
websites such as THOMAS report that action
has occurred on legislation of interest to you.

Initial published description of the RRAW-P process
Mar 2nd, 2005 by JTJ

It was in the early '90s, when JTJ began thinking about and researching
the process that results in the journalist's product.  It
eventually boiled down to the RRAW-P process:
Research–>Reporting–>Analysis–>Writing and finally
Publishing/Producing/Packaging.  The attached paper first appeared
in the Social Science Computer Review in 1994.
