Teaching Stats for Data Science

摘要

"Data science" is a useful catchword for methods and concepts original to the field of statistics, but typically being applied to large, multivariate, observational records. Such datasets call for techniques not often part of an introduction to statistics: modeling, consideration of covariates, sophisticated visualization, and causal reasoning. This article re-imagines introductory statistics as an introduction to data science and proposes a sequence of 10 blocks that together compose a suitable course for extracting information from contemporary data. Recent extensions to the mosaic packages for R together with tools from the tidyverse provide a concise and readable notation for wrangling, visualization, model-building, and model interpretation: the fundamental computational tasks of data science.
