A biоlоgist is studying territоriаlity in three relаted species of birds found in the sаme section of a forest. For each observed pair of nesting adults, the biologist measured the distance to the next closest nesting pair of the same species (nearest-neighbor distance). An analysis of the results is shown in the table below. Nearest-Neighbor Distances in Nesting Adults Species Mean Nearest-Neighbor Distance (km) Median Nearest-Neighbor Distance (km) Range of Nearest-Neighbor Distances (km) I 0.35 0.47 0.25 - 0.50 II 0.31 0.32 0.30 - 0.32 III 0.80 1.10 0.10 - 1.50 Which of the following would be most appropriate for identifying the species with the most even distribution of nests?
