What's the difference between inaccuracy and precision?

Inaccuracy


Definition:

  • (n.) The quality of being inaccurate; want of accuracy or exactness.
  • (n.) That which is inaccurate or incorrect; mistake; fault; defect; error; as, in inaccuracy in speech, copying, calculation, etc.

Example Sentences:

  • (14) Using the "Bi-Digital O-Ring Test Imaging Technique", the author has been able to accurately localize meridians and acupuncture points that correspond to specific internal organs and has found that most general patterns of meridians and the number of acupuncture points on each of the meridians of specific internal organs of the 12 main internal organs described in the literature of ancient Chinese medicine, are more or less correct, with the exception of some variations and inaccuracies.
  • (15) Intermittent or inadequate discharge of bacteria from the renal parenchyma is suggested as the major source for this inaccuracy.
  • (16) The inaccuracy in latency was measured as a function of stimulation level.
  • (17) At lower levels the results were somewhat more erratic due to inaccuracies of the various methods at low concentrations.
  • (18) The computational issues investigated were (1) computation of the regularization parameter; (2) effects of inaccuracy in locating the position of the heart; and (3) incorporation of a priori information on the properties of epicardial potentials into the regularization methodology.
  • (19) How a society deals with disability and employment, both helping people into work and protecting those unable to work, reflects its moral core – whether it opts for evidence, fairness and support, or the current methods of inaccuracy, targets and abandonment.
  • (20) This paper elucidates their mutual relationship and corrects biographical inaccuracies concerning George Huntington and George Sumner Huntington.

Precision


Definition:

  • (n.) The quality or state of being precise; exact limitation; exactness; accuracy; strict conformity to a rule or a standard; definiteness.

Example Sentences:

  • (1) A progressively more precise approach to identifying affected individuals involves measuring body weight and height, then energy intake (or expenditure) and finally the basal metabolic rate (BMR).
  • (2) They more precisely delineate the hazard identification process and the factors important in supporting risk decisions for developmental toxicants than does any other document.
  • (3) The determination of basic levels of TSH is more sensitive and more precise.
  • (4) The greatest advantages of spinal QCT for noninvasive bone mineral measurement lie in the high precision of the technique, the high sensitivity of the vertebral trabecular measurement site, and the potential for widespread application.
  • (5) It now seems clear that greater precision can be achieved through modification of the original technique.
  • (6) Validation studies, to show that the method is precise, accurate and rectilinear, have been carried out on four linctus formulations and two pastille formulations.

  • (8) Compared to the SRK II-equation the results of the new programme are much more precise.
  • (9) However, while the precise nature of the city’s dietary problems is hard to pin down, the picture regarding physical activity is much clearer.
  • (10) Labelling of the albumin with 99mTc ensured an accuracy of measurements only limited by the precision of the weighing.

  • (12) These results strongly suggest that urinary GAGs determination is a precise method for ovulation detection.
  • (13) While the precise function of the MIRP is not known, the availability of this protein in pure and biologically relevant quantities will allow further studies to elucidate its pathobiologic function.
