Similarity in the normalized rank diversity across sports and games. Plot showing a comparison of the rank diversity \(d(k)\) for all activities considered. With the values of μ and σ we obtained from the fit Φ, we have rescaled the abscissa. As reference we include the basic form of Eq. (5) (thick red line), with \(\mu=0\) and \(\sigma =1\). These results indicate that all activities have the same functional shape of rank diversity.
