Description Welcome to data science's dirty secret: real-world data is messy. Data scientists must spend a good deal of time playing software developer, writing code to clean up data before they can actually do anything constructive with it.
It's a necessary evil, but you can still make the most of it. This practical book walks you through several real-world examples to demonstrate the theory and practice behind working with and cleaning up dirty data.

Fortunately, we were able to meet, via email and phone, a wonderful scientist named Katherine Muzik. It turns out she is one of the pre-eminent experts on coral, and her current project, "Mala Moana" "Ocean Garden" , entails transplanting a special variety of coral that appears to be resistant to the environmental effects that have killed much of the rest of the coral around Kauai.
We love Kauai, and my wife especially loves snorkeling around Kauai, and we've been distressed as we've watched the decline of the reefs over the years.
While we've been active in other charitable areas over the year particular around horse welfare and rescue, including rescuing several ourselves, and donating the use of our property to a horse rescue organization , we've never been more than concerned and hopefully conscientious tourists with respect to Kauai. But meeting Katherine inspired us to try to help, so we put together a calendar with pictures of Kauai that Jessica has taken over the years that we've been visiting.
The main pictures are all of Honu Hawaiian Green Sea Turtles , with smaller pictures representative of the many amazing sites on Kauai. Visit HonuCalendar.
My chapter describes an approach to assessing the quality and quirks of a data set, with several real-world examples that I've encountered in the past couple of years.
