Chimpanzee right‐handedness reconsidered: Evaluating the evidence with funnel plots

Chimpanzee right‐handedness reconsidered: Evaluating the evidence with funnel plots Evidence for population‐level right‐handedness in nonhuman primates seems inconsistent and contradictory, and many hypotheses have been advanced to account for this volatility. Funnel plots (scatter plots of percent right‐hand use vs. sample size) offer a straightforward graphical technique for assessing: 1) the strength and consistency of handedness, 2) whether variability is consistent with normal sampling variation, and 3) how likely reports of statistically significant handedness might have arisen due to chance (i.e., type I error). They are informative for both within‐ and among‐population variation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png American Journal of Physical Anthropology Wiley

Abstract

Evidence for population‐level right‐handedness in nonhuman primates seems inconsistent and contradictory, and many hypotheses have been advanced to account for this volatility. Funnel plots (scatter plots of percent right‐hand use vs. sample size) offer a straightforward graphical technique for assessing: 1) the strength and consistency of handedness, 2) whether variability is consistent with normal sampling variation, and 3) how likely reports of statistically significant handedness might have arisen due to chance (i.e., type I error). They are informative for both within‐ and among‐population variation.
