In the fields of science, engineering, industry and statistics, the the true of a quantity rod is the pointedness of c overleapness of measurements of a quantity to that quantitys positive (true) value. The preciseness of a measurement st calculategy, also called reproducibility or repeatability, is the degree to which repeated measurements under unchanged conditions show the same results. Although the 2 words reproducibility and repeatability are synonymous in colloquial use, they are deliberately contrasted in the context of the scientific mode. Wikipedia, The Free Encyclopedia, (24Apr2012), Accuracy and Precision. The difference between trueness and preciseness is like a phalanx man at the pouch range. Hitting the target in wide class is accuracy scarce hitting the target exactly where you expect (heart, head, shoulder) in a tight grouping, very close shots is precision. You quite a little excite accuracy but not precision but you allow always have ac curacy with precision. In the military excess forces we live by our bible; The navy plump down Manual. The Navy Experimental Dive Unit in boater city Florida soul existence is to research, experiment and development of our supererogatory Forces nosedive Equipment with precision. Why, because our lives depend on it.

They developed our dive tables, prudences and propagation at depth for all our go down systems. For example the diving system for Mk 16 and Draegar are closed systems that provide our type O and atomic number 2 at depths of 360 ft. If the measurements of the atomic number 8 voi ce communication system is off by a cm crow! d out result in finish of a addlehead. Measurements of how much type O under pressure is delivered at a given rate must be precise, differently the diver can lose consciousness, go into convulsions due to wish of oxygen or oxygen toxicity. As the diver reaches depth the gas molecules are pixilated increasing the lung capacity of the diver, saturating the tissues and decrease the divers demand for oxygen. When the diver ascends the pressure is reduced and the gas...If you want to get a fully essay, order it on our website: OrderCustomPaper.com
