Welcome to the 5.2 edition of A Portable Introduction to Data Analysis.

This is a small update to the Fifth Edition which brings it in line with the Islands, a new virtual population to support learning in experimental design, epidemiology and statistical reasoning. Many examples and exercises have been updated to reflect this. Various other changes have been made to improve consistency and all known errata have been corrected.

The Fifth Edition itself was extensively revised to bring key topics such as hypothesis testing much earlier in the text. Randomization tests were also adopted to support and illuminate traditional algebraic methods.

This book is now available online as an Open Textbook at https://uq.pressbooks.pub/portable-introduction-data-analysis.
