Question:
Hyenas, famously, laugh. (The technical term used by hyena biologists is “giggle.”) Mathevon et al. (2010) investigated the information content of hyena giggles. In one analysis, they compared the giggles of pairs of hyenas, in which one member of each pair was the more dominant and the other socially subordinate. They measured the spectral variability of the hyena giggles using the coefficient of variation (CV) of sound spectrum features. Here are the data with these measures for each member of the pairs:
Do dominant and subordinate individuals differ in the means of giggle spectral CV?
