The Repeatability is the degree of agreement between independent test results produced by the same analyst, using the same test method and equipment on random aliquots of the same sample within a short time period.

Replacement Heifers are Often ones being raised to replace the cows currently in the herd.

Replacements Heifers are Often ones being raised to replace the cows currently in the herd.

A Replicate is a duplicate, copy, or repeat of an element, item, or process, often used to develop an average value or to assess the sources of variability and error.

The Reporting Limit is the minimum value below which data are documented as non-detected.

A Representative Sample is a subset of a population that is supposed to reflect what should occur under normal operating conditions.

representativeness are "The degree to which data accurately and precisely represent the Frequency distribution of a specific variable in the population; a data quality indicator" (QAMS 1993, 20).

The Reproducibility is the precision, usually expressed as variance, which measures the variability or closeness among the results of measurements of the same sample at different laboratories by different operators.
