itns-package: Datasets for the book Introduction to the New Statistics

In gitrman/itns: Datasets from the book Introduction to the New Statistics

Description

The itns 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.

Details

The original source of the datasets is a series of Excel files found on the Introduction to the New Statistics website. Those Excel files have been converted to R data frames and bundled together in the itns package. In addition:

• All variable names have been converted to lower case.

• For some data sets, variable names have been altered in order to conform with R data naming rules (e.g., some variable names in the Excel files started with a number, which is not allowed in R).

• Some datasets have been tidied using the tidyr package in order to facilitate analyses in R.

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.

Also included is a function to compute Cohen's d effect size for paired samples.
