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.

Nursing theory: its importance to practice. Colley S(1). Author information: (1)University Hospital Wales, Cardiff. sarahj27@lycos.co.uk. BACKGROUND: Nursing theory should provide the principles that underpin practice and help to generate further nursing knowledge.However, a lack of agreement in the professional literature on nursing theory confuses nurses and has caused many to dismiss nursing theory as irrelevant to practice.his article aims to identify why nursing theory is important in practice. CONCLUSION: By giving nurses a sense of identity, nursing theory can help patients, managers and other healthcare professionals to recognise the unique contribution that nurses make to the healthcare service (Draper 1990).
