Assessing the Function of House Sparrows' Bib Size Using a Flexible Meta-Analysis Method

Description

A meta-analysis on the association between the size of a male's bib and their social status in house sparrows (Passer domesticus).

Usage

dat.nakagawa2007

Format

The data frame contains the following columns:

StudyID	character	identity of primary study
Place	character	location of study population
Correlation	numeric	correlation coefficient
SampleSize	integer	sample size of population

Details

Each study measures the association between a sparrows bib size and its social status. Effects are quantified as correlation coefficients.

Concepts

ecology, correlation coefficients
