Land Area and Mammal Species


Land area and number of mammal species for islands in Southeast Asia


A dataset with 14 observations on the following 5 variables.

Name Name of the island
Area Area (in sq. km)
Species Number of mammal species
logArea Natural logarithm (base e) of Area
logSpecies Natural logarithm (base e) of Species


This dataset shows the number of mammal species and the area for 13 islands in Southeast Asia. Biologists have speculated that the number of species is related to the size of an island and would like to be able to predict the number of species given the size of an island.
