...l for example show consistent levels of aggression and differ from others in a consistent manner. I thought that I could tackle this question using repeatability, defined as r = sa^2 / (sa^2 + s^2) where sa^2 is the among-groups variance component and s^2 is the within-group variance component (Lessells & Boag, 1987).
