But if you're trying to extract useful information from an ever-increasing inflow of data, you'll likely find visualization useful -- whether it's to show patterns or trends with graphics instead of mountains of text, or to try to explain complex issues to a nontechnical audience.

But as with human sources, you have to ask! So what should you ask a number? Well, mathematicians have developed an entire field — statistics — dedicated to getting answers out of numbers. Now, you don't have to have a degree in statistics in order to conduct an effective "interview" with your data. But you do need to know a few basics. In 1996, I first published Statistics Every Writer Should Know, an online tutorial for math-phobic journalists. Running a business demands at least a basic knowledge of math and math concepts, so I'm including this tutorial as an appendix my 2012 book, How to Make Money Publishing Community News Online.

Find out where hidden data is and try and get hold of it: private companies looking for publicity, under appreciated research departments, public bodies that release data but not in a granular form (e.g. Test out cleaning/visualisation tools: You want to be able to collect data, clean it, visualise it and map it.
Code. How to be a data journalist. Data journalism is huge.
I don't mean 'huge' as in fashionable - although it has become that in recent months - but 'huge' as in 'incomprehensibly enormous'. It represents the convergence of a number of fields which are significant in their own right - from investigative research and statistics to design and programming. The idea of combining those skills to tell important stories is powerful - but also intimidating. Who can do all that? The reality is that almost no one is doing all of that, but there are enough different parts of the puzzle for people to easily get involved in, and go from there. 1.

How do you avoid sending yourself and your shiny “speed of thought” tool slamming into a dead end? Dan Murray’s got a routine — and he’s also got certain music and right-brained books to go along. Dan’s first rule: “Don’t pre-think.” It’s the hardest thing for people to learn, he says. “If you go into [data analysis] thinking you know where you’re going, you easily miss the granule of gold.” He’s the chief operating officer and heavy-hitting data analyst at InterWorks, Inc., an Oklahoma-based business consultancy. From an airport somewhere in the South, he explains, “You have to think like a writer thinks. He’s been analyzing data ever since spreadsheets first became available in the early ’80s. The routine goes something like this. First, get the big picture. Look for what pops out. Find groups. Lay out timelines.

Data journalism training – some reflections. I recently spent 2 days teaching the basics of data journalism to trainee journalists on a broadsheet newspaper.
It’s a pretty intensive course that follows a path I’ve explored here previously – from finding data and interrogating it to visualizing it and mashing – and I wanted to record the results. My approach was both practical and conceptual. Conceptually, the trainees need to be able to understand and communicate with people from other disciplines, such as designers putting together an infographic, or programmers, statisticians and researchers.
They need to know what semantic data is, what APIs are, the difference between a database and open data, and what is possible with all of the above. They need to know what design techniques make a visualisation clear, and the statistical quirks that need to be considered – or looked for.
