Average is ALWAYS the sum/n; n = number of discrete values. If you think of it in terms of a moving submarine, the submarine goes down 17.21 meters, then goes up 7.90 meters. Final position is -9.31 meters. So on average he went down 4.655 meters per move.
So, with that being said I turn to McGonigle and Mastrian (2009) and their definition of Nursing Informatics which is the âcombination of nursing science, information science and computer science to manage and communicate data, information, knowledge, and wisdom in nursing practiceâ (p. 5).
IMPORTANCE OF NURSING THEORIES. 1  Nursing theory aims to describe, predict and explain the phenomenon of nursing (Chinn and Jacobs1978). 2  It should provide the foundations of nursing practice, help to generate further knowledge and indicate in which direction nursing should develop in the future (Brown 1964). A particular theory or conceptual frame work directs how these actions are carried out. 2  The delivery of nursing care within the nursing process is directed by the way specific conceptual frameworks and theories define the person (patient), the environment, health and nursing.
