Data sets that accompany the book "Designing experiments and analyzing data: A model comparison perspective" (4th ed.) by Maxwell, Delaney, and Kelley (2027; ISBN 978-1-041-25384-6; Routledge). Contains all of the data sets in the book's chapters and end-of-chapter exercises. Beginning with version 2.0, the package is tailored to the 4th edition of the book; for the data as distributed with the 3rd edition (2018), install the archived version 1.0.2 from CRAN. We recommend the 'DMAR' package as the companion for carrying out the book's analyses; these analyses are illustrated in the book itself using the 'MBESS' package, which may be used as well. The book's companion website is available at < https://designingexperiments.com/> and its publisher page at < https://www.routledge.com/Designing-Experiments-and-Analyzing-Data-A-Model-Comparison-Perspective/Maxwell-Delaney-Kelley/p/book/9781041253846>.

AMCP provides all of the data sets used in Maxwell, Delaney, & Kelley's Designing Experiments and Analyzing Data: A Model Comparison Perspective (Routledge). There are no functions in this package; it contains data only.
The package's major version tracks the edition of the book: AMCP 2.x is for the book's 4th edition (Maxwell, Delaney, & Kelley, 2027), and AMCP 1.x is for the book's 3rd edition (2018).
Install the current release (AMCP 2.x, for the book's 4th edition) from CRAN:
install.packages("AMCP")
If you are using the book's 3rd edition (2018), install the last 1.x release from CRAN instead, which ships the data as distributed with that edition:
# install.packages("remotes")
remotes::install_version("AMCP", version = "1.0.2")
We recommend the DMAR package as the companion for carrying out the book's analyses. Install it with:
install.packages("DMAR")
The book itself illustrates these analyses using the MBESS package, which you can use as well.
