Committing fact errors in visualizations

January 18th, 2010

At Medill, there’s a wonderful tradition called the “Medill F.”  Make a factual error of any sort, and you fail the assignment.  The sadistic part of me likes it — a journalist’s job is to tell the truth.  If you miss the mark, you’ve failed the public, and failed at your job for the day. Harsh but true. My only Medill F was writing down the wrong day for an exhibit closing. I’ll never forget that one.

Why do you care, you ask?  Because it’s an example of just how simple it is to make a factual error.  That’s something I’ve been thinking about a lot recently.  (more…)

Collaborating with computers to parse “big data”

January 18th, 2010

Picture it: You've been given a new story assignment, and you have to leave for the interview in five minutes. You've got to have enough background to ask the right questions, but there's no time to do research.  Somehow pulling that all-nighter on an English term paper in college seems like a cakewalk Read More...

Data Delver: Ted Mellnik, Charlotte Observer database editor

January 12th, 2010

Computer-assisted reporting is important because of its potential for reporting and analysis.  Visualization is important to present the information to readers. They both fall under the responsibilities of Ted Mellnik, database editor at the Charlotte Observer. His passion for data is as clear from a conversation with him as it is from his work Read More...

Why technology matters: It’s about reporting

January 11th, 2010

"Figure out what you want to do, and get really good at it."  That's been the overarching advice I've heard in the past few weeks, as I seek to understand where I might fit in the "new media" world.  It all sounds fine, although the more I meet interesting people who've been looking at data analysis and web presentation for a long time, the more it becomes apparent that getting "really good at it" is a lifelong endeavor Read More...

Importance of combining data analysis with context (reflections on readings from week two)

January 11th, 2010

"Visual and Statistical Thinking: Displays of Evidence for Making Decisions," Edward Tufte, Visual Explanations This chapter gave practical examples of something I've been saying from almost the first day of my data analysis journey -- that it's absolutely fundamental that the decisions behind the analysis are shown to the reader/user Read More...

A list of 40 CAR-friendly news organizations
(my adventures in parsing the IRE directory)

January 11th, 2010

Sure, data-driven reporting investigations sound good, but how does an aspiring journalist know which organizations are most supportive of that kind of work? I don't believe there's one all-encompassing way to tell, but I would argue that one measure might be the number of Investigative Reporters and Editors-card-carrying members in a news organization Read More...

Which states have been hit hardest by unemployment in the last decade?

January 10th, 2010

For the past week, we've been hearing a lot of media coverage focusing on issues both encouraging and discouraging, looking with excitement at the beginning of a new decade. But what captured my attention most recently was the release of unemployment figures from the end of 2009. If you look at the glass as half full, it's got to go up from here sometime soon, and if you look it as half empty, we're not starting in a strong economic place Read More...

Reflections on Visualization Theory (Data viz readings, week 1)

January 4th, 2010

In this first set of reading, I learn that the principles of simplicity, accuracy and more are as true in data visualization as they are in a text story. Edward Tufte, Visual Explanations, "Images and Quantities" In Tufte's first paragraph of Visual Explanations, he discusses the importance of readability -- a concept I see as having a strong parallel to the usability so often discussed in a more modern era Read More...

My new perspective on math – it’s a journalistic tool!

January 4th, 2010

Tomorrow, Jan. 4, means the beginning of an end to my formal graduate education. It's the first day of my final quarter at Medill. I'll be returning to the Evanston campus for the first time since June 2009, primarily for an independent study on data visualization with Medill professor Rich Gordon Read More...

Changes in how we travel across U.S. borders

December 30th, 2009

Traveling is something we often take for granted nowadays -- at least, I know I do.  And as situations in my life have changed, I've been thinking about all the different types of transportation I use.  I'm a bit more reliant on my car in the Chicago suburbs, and while I griped about the Metro while in D Read More...
