前言

WHEN WE WERE FIRST APPROACHED WITH THE IDEA OF A FOLLOW-UP TO BEAUTIFUL CODE, THIS TIMEabout data, we found the idea exciting and very ambitious. Collecting, visualizing, andprocessing data now touches every professional field and so many aspects of daily life thata great collection would have to be almost unreasonably broad in scope. So we contacted ahighly diverse group of people whose work we admired, and were thrilled that so manyagreed to contribute.This book is the result, and we hope it captures just how wide-ranging （and beautiful）working with data can be. In it you'll learn about everything from fighting with govern-ments to working with the Mars lander; you'll learn how to use statistics programs, makevisualizations, and remix a Radiohead video; you'll see maps, DNA, and something we canonly really call "data philosophy."

内容概要

章节摘录

插图：We then purchased an inexpensive data set of IP-to-State information. With it, we wereable to match each IP address collected with the U.S. state in which it resided. Althoughwe could have scripted our pages to access this database and match the numbers at thetime of data collection, we chose to do the matching semi-automatically after the fact. Forstarters, the project budget and timeframe did not warrant purchasing the additionalserver power to handle the task. But more important, from a user perspective, was thedelay this matching would have inevitably built into the survey completion process.Although it might have been more convenient for us to receive finalized data at once, itwould have created an additional inconvenience for our user. When designing a data col-lection experience, it's important to think about what server tasks must take place duringthe survey in order for the user's needs to be met, and what tasks can be delayed until afterdata collection. Don't ask the user to do what you can do——or discover——on your own.All of this leads us back to the central point of this chapter, which is also the final, andcore, aspect of building trust: treat the respondent with respect. By demonstrating thatyou value the respondent and her time and intelligence, by interacting with her in a Con-versational manner （despite the fact that all survey questions are being delivered by a pre-programmed machine）, and showing her that you've been "listening" to her answers（don't, for example, ask slight variations of the same question over and over again, whichmakes it seem as though you didn't pay attention to her original response）, you'll increasetrust, encourage real answers, and keep the respondent from disengaging.
