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:

  • (1) For data sampled at a high rate (approximately 200 Hz) pupil velocity deviations from zero can simply be used, giving a satisfactory inaccuracy of about 5 ms. For data sampled at a low rate (less than 50 Hz), e.g.
