Essential Statistics for Data Science

A Concise Crash Course

Mu Zhu

Essential Statistics for Data Science: A Concise Crash Course is for students entering a serious graduate program or advanced undergraduate teaching in data science without knowing enough statistics. The three part text introduces readers to the basics of probability and random variables and guides them towards relatively advanced topics in both frequentist and Bayesian in a matter of weeks.

Part I, Talking Probability explains the statistical approach to analysing data with a probability model to describe the data generating process. Part II, Doing Statistics demonstrates how the unknown quantities in data i.e. it's parameters is applicable in statistical interference. Part III, Facing Uncertainty explains the importance of explicity describing how much uncertainty is caused by parameters with intrinsic scientific meaning and how to take that into account when making decisions.

Essential Statistics for Data Science: A Concise Crash Course provides an in-depth introduction for beginners, while being more focused than a typical undergraduate text, but still lighter and more accessible than an average graduate text.

Readership : Advanced undergraduate and graduate students in quantitative disciplines; software engineers; and various information technology (IT) professionals.

Special Features

  • A very short (but serious) course that can be taught in just a few weeks
  • Still goes from "the very beginning" [e.g., P(not A)=1-P(A)] to relatively advanced materials (e.g., EM algorithm, Gibbs sampler) despite its lightning pace and introductory nature
  • Treats Bayesian inference right after frequentist point estimation, but before topics such as interval estimation and significance testing, unlike most other texts
