'Ipiña SL, Durand AI, 2010: Some considerations on the use of the quotient of sample means as a measure of sexual dimorphism. Anthropologie (Brno) 48, 1: 1-4'. |

Abstract | Assuming we are sampling from independent normal populations, the quotient of sample means is probably the most popular measure of sexual dimorphism found in the anthropological literature. However, it is used as a descriptive (vs. inferential) sample function in spite of its evident relationship with the difference of two sample means. Here we discuss some aspects of the use of this quotient, like its reliance on the independence assumption between sexes, and show a simple procedure that involves applying to the quotient of sample means the inferences that can be drawn from the difference of sample means. | | Keywords | Sexual dimorphism measure - Sample means quotient - Independence - Student's t-distribution | |
