Author: Source: Unknown - Date unknown Please cite: This dataset contains 3 more features compared to version 1 of the same dataset. Data from which conclusions were drawn in the article "Sleep in Mammals: Ecological and Constitutional Correlates" by Allison, T. and Cicchetti, D. (1976), _Science_, November 12, vol. 194, pp. 732-734. Includes brain and body weight, life span, gestation time, time sleeping, and predation and danger indices for 62 mammals. Variables below (from left to right) for Mammals Data Set: species of animal body weight in kg brain weight in g slow wave ("nondreaming") sleep (hrs/day) paradoxical ("dreaming") sleep (hrs/day) total sleep (hrs/day) (sum of slow wave and paradoxical sleep) maximum life span (years) gestation time (days) predation index (1-5) 1 = minimum (least likely to be preyed upon) 5 = maximum (most likely to be preyed upon) sleep exposure index (1-5) 1 = least exposed (e.g. animal sleeps in a well-protected den) 5 = most exposed overall danger index (1-5) (based on the above two indices and other information) 1 = least danger (from other animals) 5 = most danger (from other animals) For more details, see Allison, Truett and Cicchetti, Domenic V. (1976), "Sleep in Mammals: Ecological and Constitutional Correlates", _Science_, November 12, vol. 194, pp. 732-734.
