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).
Informatics nurse specialists have multiple roles. They are often the go-between between the nursing staff and IT. According to the University of Maryland, jobs in nursing informatics fall in two broad categories: applied/professional and expert/ liaison roles. The applied roles are the more techie ones. Some informatics nurse specialists are on the team that develops new software systems. Specialists in the liaison role, meanwhile, may do needs assessment, select appropriate systems, and prepare training materials. Nursing informatics is generally not a persons first job.
