The Art of Data Science (The Book + Lecture Videos)
The Art of Data Science
A Guide for Anyone Who Works with Data
About the Book
Data analysis is a difficult process largely because few people can describe exactly how to do it. It's not that there aren't any people doing data analysis on a regular basis. It's that the process by which we state a question, explore data, conduct formal modeling, interpret results, and communicate findings, is a difficult process to generalize and abstract. Fundamentally, data analysis is an art. It is not yet something that we can easily automate. Data analysts have many tools at their disposal, from linear regression to classification trees to random forests, and these tools have all been carefully implemented on computers. But ultimately, it takes a data analyst—a person—to find a way to assemble all of the tools and apply them to data to answer a question of interest to people.
This book writes down the process of data analysis with a minimum of technical detail. What we describe is not a specific "formula" for data analysis, but rather is a general process that can be applied in a variety of situations. Through our extensive experience both managing data analysts and conducting our own data analyses, we have carefully observed what produces coherent results and what fails to produce useful insights into data. This book is a distillation of our experience in a format that is applicable to both practitioners and managers in data science.
If you are interested in obtaining a printed copy of this book, you can purchase one at Lulu.
The package containing the lecture videos offers short commentaries on each of the chapters and contains addtional explanatory material for each of the topics. In addition there is some material in the lectures that is not included in the book.
Packages
The Book + Lecture Videos
This package includes the book and lecture video files. The videos and chapters are aligned so that together they make an ideal self-learning curriculum in which students interested in data science can pair video lectures with reading material. The videos complement the reading material by extending concepts covered in the book and by providing visual and auditory presentation of the concepts. This self-guided curriculum can be covered at any pace and the completion of material should provide students with a solid foundation for thinking about the data science process. The complete package should be of interest to students interested in doing their own data analyses and to people who need to manage data science teams.
