Fig. 5From: Repeatability of endocrine traits and dominance rank in female guinea pigsScatterplot of rank index calculated for each individual at the first (x axis) and second (y axis) observation. The two housing groups are designated by shape and color. Rank index was significantly repeatable (R = 0.709; p = 0.007). Line of best fit is plotted for visualization of the relationship from basic linear regression (second observation ~ first observation)Back to article page
