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).
Now, nursing is considered a science and an art, and the delivery of nursing care requires understanding the science that guides nursing practice. Using the science to help patients meet their health goals is what evidence-based practice is all about. EBP is important because it means better care, safer care, and lower health care costs. Evidence-based practice leads to better patient outcomes and also protects the nurse's practice.
