The Art of Statistics: Code, Data, Errata and Additions

UK hardback: UK paperback: US hardback:

Here is the book’s UK Amazon page and US Amazon page

The UK and US hardback versions are identical in content. Errata and additions are listed below for all versions.

This file is produced by R Markdown, and there is also a web-page produced by Github.

Code repository

The repository contains data and R code for the Figures and Tables in Art of Statistics. They should all work in RStudio.

  • It is not yet complete, and will change and improve.

  • The graphics were originally mainly produced in basic R, but (with much appreciated assistance) these have been mainly revised into ggplot2 - sometimes both versions are provided for comparison. However I do not pretend to have any particular skill in using R or ggplot, and no doubt many improvements could be made.

  • Many packages are used and will need to be installed, for example using install.packages(“ggplot2”)

  • While the individual files can be downloaded, it is probably easiest to download a zipped repository using the green download button.

  • page 179 para 2, line 5 replace "When a vision algorithm was trained to discriminate pictures of huskies from German Shepherds, it was very effective until it failed on huskies that were kept as pets – it turned out that its apparent skill was based on identifying snow in the background" by "A vision algorithm intended to discriminate pictures of huskies from wolves was (deliberately) trained on images of wolves in snow and huskies without snow, with the result that any future image of either dog was classified as a wolf if there was snow in the background"

    r = \frac{ \sum_{i=1}^n (x_i - \overline{x})(y_i - \overline{y}) } { \sqrt{\sum_{i=1}^n (x_i - \overline{x})^2 \sum_{i=1}^n (y_i - \overline{y})^2 }}.

  • page 396 Pearson Correlation Coefficient. Add \frac{1}{n} before \sum_{i=1}^n u_i v_i

  • page 396 Pearson Correlation Coefficient. Add after ‘Z-scores’ ‘(this assumes the standard deviations have been calculated with n in the denominator: if n-1 has been used, the formula is \frac{1}{n-1}\sum_{i=1}^n u_i v_i
