Introduction

Welcome to the online content for Statistics Without Calculations

The book can be used standalone, without needing to access any of this online content.

The online content here provides six kinds of extras:

1. Interactivities

Each chapter has at least one interactive app, created in Shiny. These allow you to play around with some of the ideas from the chapter and explore what happens.

They are all linked from the Interactivities page.

2. Answers to Chapter Questions

Detailed answers to the questions at the end of each chapter are available on the Chapter Answers page.

3. Answers to Case Study Questions

Detailed answers to the case study questions at the end of each chapter are available on the Case Study Answers page.

4. PowerPoint Files

PowerPoint files for each chapter are available on the PowerPoint Files page.

5. Analysis online

A page is available for each chapter showing you how to do the statistical analyses described in that chapter for yourself. One possible way to use the book is to ignore this content the first time you read the book, but use it on a second read through.

There are full details on the main page. There’s no need to download or install any software, as the R code will run in any web browser on a computer or mobile phone, using WebR.

To do the analyses offline, without using WebR, download the latest versions of R and RStudio for free from https://cran.r-project.org/ and https://posit.co/downloads/ and follow the instructions there.

6. Data sets

The fictitious data sets used in the book are available at https://github.com/colinfoster77/Stats.

We use these in the Analysis content for each chapter to reproduce the analyses discussed in that chapter.
