I've been fortunate to have worked with people from lots of different fields - statistics, ecology, computer science, engineering, design, etc. If I've learned anything, it's that everyone has a different idea of what data is and why it matters.

I've found that until I've understood what my collaborators mean by data and what they (and me) are trying to get out of a dataset, it's near impossible to get anything useful done.

To make things a bit more clear (and for my own enjoyment), I asked a select group of people a single question:

What is data and why should we care about it?

Those who responded are from different areas of expertise, ranging from statistics, to business, to computer science, to design. Some names you'll recognize while others will be new to you. All are doing interesting things with data.

I've been looking forward to this series for a couple of weeks now, and my hope is that you will gain a better understanding about what data is and how people are putting it to use. Keep an eye out for posts with the black square image above.
