This is the companion site to the electronic textbook, Introduction to Data Science, by Jeffrey Stanton. This book provides non-technical readers with a gentle introduction to essential concepts and activities of data science. For more technical readers, the book provides explanations and code for a range of interesting applications using the open source R language for statistical computing and graphics.
This book was developed for the Certificate of Data Science program at Syracuse University’s School of Information Studies. If you find errors or omissions, please contact the author, Jeffrey Stanton, at jmstanto@syr.edu.
