Finished: The JASP Data Library (1st ed.)

In a previous post, “Hell is other people’s data”, we introduced a first attempt to document the 50 data sets that constitute the JASP Data Library. At the time, we only had a preface and two chapters. We are happy to report that all 50 data sets have now been documented. Each of the 50 chapters follows the JASP data documentation format (JDDF), which provides detailed guidelines on how to archive data such that its origin, purpose, and meaning is clear, and reanalysis is relatively straightforward. The JDDF recommends that data archiving should be accompanied by an example analysis, and therefore each of the 50 chapters provides an analysis in JASP. Below is a screenshot of the first page of chapter 23, “Alcohol Attitudes: 3 x 3 Repeated Measures ANOVA”.

The book is typeset in Tufte style (with special thanks to Kevin Godby) and totals 426 pages. Many of the examples are taken with permission from two popular statistics textbooks: Field (2017) and Moore, McCabe, & Craig (2012). Our entire book is available for free here.

For those of you who would like to archive their own data using the JASP guidelines we have made a template available here. Please let us know if you would like your data set to be added to the Data Library!
