A dataset consisting of 83 empirical studies used in the meta-analysis of Pietschnig, Penke, Wicherts, Zeiler, and Voracek (2015) on the associations between human brain volume and intelligence (measured full-scale IQ) in healthy participant samples.
A data frame with 83 rows and 8 variables:
short name of each study
publication year of each study
observed correlations between intelligence and brain size
Fisher's z transform of the observed correlations for meta-analysis
Standard error of Fisher's z transformed observed correlations for meta-analysis
sample size of each study
categorical moderator variable: gender of the participants in each study
continuous moderator variable: mean age of all participants in each study
