Fig. 2

Rose plots for the Mood Rhythm Instrument (MRhI) time variables divided by groups of sex. The circle represents 24 h and each bin represents a 3-h period. The petals magnitudes are based on the proportion of participants of each group presenting a daily peak in the corresponding 3-h period. The bin width is divided equally by the two groups and the petals are laid out sequentially in the bin. The lines represent the circular mean for each group. Men and women do not differ in any MRhI item considering a level of significance of α = 0.05 (Mardia-Watson-Wheeler test for equal distributions)
