Observer bias in selection of study group in baboon field studies
Sharman M., Dunbar RIM.
Analyses of data from field studies of baboons (genus Papio) show that observers tend to select the largest groups available to them in their study populations up to a limiting group size of about 80-100 animals. This is likely to introduce significant biasses into eco-correlate analyses whenever group size is an important independent variable. © 1982 Japan Monkey Centre.
