Artifact Corrections for Effect Sizes

Seeing Reality for What it is

Greetings

Welcome to the living open source textbook Study Artifacts and Their Corrections. This book is designed to assist social/clinical/behavioral/cognitive researchers in understanding the nature of study artifacts, their impact on effect sizes, and proper correction methods. Each chapter includes practical examples, R code, and equations for seamlessly implementing these corrections into your own research projects.

What are Study Artifacts?

In this book, artifacts will be defined broadly as any source of methodological contamination that induce bias in research findings. In an ideal world where studies are conducted perfectly, this book would not exist. Hopefully one day, we reach a point where studies contain only small, inconsequential imperfections and this book becomes obsolete, a relic of a darker past. Until that day, artifact corrections can provide a temporary band-aid to some methodological flaws.

Open and Living Textbook

A living textbook is one that continuously updates with new features and is open to changes from others. This book will contain modern methods and cutting-edge techniques for artifact corrections, so in order to keep this book up-to-date it needs to grow as the research grows. It is important that this book is both open-source and open-access. All the figures, code, and documents are available on Github.

Versioning

Currently the book is a work in progress and is in a beta phase. Version 1.0 will be coming be coming out in the fall. Versions will be stored in the following Zenodo repository: and Zenodo.
