The authors of our book make many important observations about Data Science at the beginning of Chapter 7 (2e Chapter 9).
- "The objective of Data Science is to extract meaning from data."
- "Visualization is good for seeing patterns in noisy data."
- "It is important to be able to see when the patterns we see are strong enough that they are not mere accidents."
- "Statistical methods quantify patterns and their strengths."
- "Some people think that "big data" has made statistics obsolete. The argument is that with lots of data, the data can speak clearly for themselves. This is wrong, as we shall see."
- "This chapter will illustrate a Data Science workflow."
