摘要

Null-hypothesis significance testing is the primary, but not only, tool for sexual dimorphism research (1). A large variety of different indices have been developed for quantifying sexual dimorphism. Statistical tests offer better technique and a mathematically more grounded decisionmaking algorithm to test differences in size between the two sexes, but indices have advantages as well. Often it is easier to have a single numerical value to express the phe nomenon under study. Index outcomes are interpretable as scalar expressions, and similar values always indicate similar phenomena, facilitating comparisons between studies.
