ABSTRACT
Definition 13.1 Sociology is a branch of science that studies the structure, organization, operation, and development of human societies.
A human society is constructed by individuals, groups, organizations,
and sectors from the bottom up [Wiggins et al., 1994; Macionis et al., 1997]. A group is the basic social unit formed by two or more persons working towards a particular purpose. The group is needed because of the interdependency among members when a given work cannot be carried out by a single individual limited by the scarcity of either resources or functions.
