The random error observable within the time period of a single analytical run.

Imprecision, английский
- “the random dispersion of a set of replicate measurements and/or values expressed quantitatively by a statistic, such as standard deviation or coefficient of variation.” [clsi] ifcc has recommended that the mean value and number of replicates should also be stated, and the experimental design described in such a way that other workers can repeat it. this is particularly important whenever a specific term is used to denote a particular type of imprecision, such as within-run, within-day, day-to-day, total, or between-laboratories.
- Неточность. см. precision (прецизионность).
- Неточность ров частиц, осаждаемых на каждом предметном стекле, зависит от диаметра отверстия и скорости движения газа.
- Неточность. см. precision — точность.

Z-score, z-value, английский
A calculated number that tells how many standard deviations a control result is from its mean value, e.g., a control result of 112 on a material having a mean of 100 and a standard deviation of 5 has a z-score of +2.4, i.e., it is 2.4 standard deviations above its mean.
Within-laboratory precision, английский
Precision over a defined time and operators, calibration and reagents may vary within the same facility and using the same equipment. note: formerly, the term total precision was used. [clsi ep15-a2]
