Table 3:

Summary of the statistical analyses performed on 25 steroids measured in 4 brain areas and in the serum of adult male and female quail. Data for brain areas were analyzed by a two-way ANOVA for each steroid with the area considered and sex of the subjects as independent factors. Concentrations in the serum were compared in males and females by a t test for each steroid. Df= degrees of freedom.
