This R package contains datasets from psychology studies used in book Introduction to the New Statistics by Geoff Cumming and Robert Calin-Jageman, published by Routledge in late 2016. It also contains a function to compute Cohen's d effect size and a confidence interval for paired samples.

The original source of the datasets is a series of Excel files found on the Introduction to the New Statistics publisher companion website. Those Excel files have been converted to R data frames and bundled together in the itns package. The datasets can be used to replicate analyses that appear in Introduction to the New Statistics, and to work through the book's end-of-chapter exercises.

itns is not currently on CRAN, but you can install it from github using the devtools package:

 library(devtools)
 install_github("gitrman/itns")

You can read the tutorial Getting Started with the New Statistics in R, which provides an overview of the itns package, as well as other R packages and functions that can be used to conduct the analyses covered in Introdudction to the New Statistics.

You can also download a PDF version of the package manual.
