(1) A measure of the strength of the relationship between repeated records (repeated phenotypic values) for a trait in a population. (2) A measure of the strength of the relationship between single performance records (phenotypic values) and producing abilities for a trait in a population. (3) In dairy publications, accuracy of prediction.
The degree of agreement among independent measurements of a quantity under the same conditions.
the potential of the same results to be repeated over time. Repeatability is one measure to determine accuracy of measurement.
The ability of a system to reproduce or duplicate the same measurement. The total range of variation of a dimension is called the 6-sigma repeatability.
The closeness of agreement among a number of consecutive output values measuring the same input value under the same operating conditions, approaching from the same direction. Usually measured as nonrepeatability but expressed as repeatability, a percentage of span.
The ability to keep photo film and the images their on in proper register. to top
The inherent variability of the measurement device. The variability of measurements under similar conditions such as the same operator and same measurement device.
The measure of accuracy by which an instrument permits the return to a specific point. In a normal or Gaussian distribution, the results are spread roughly symmetrically about the central value, and small deviations from this central value are more frequently found than the large deviations. The normal curve can be represented by The standard deviation, denoted by is found by taking the difference between each observed particular value and the mean, then squaring the difference, adding all the squares, dividing by the number of readings, and then taking the square root.
Repeatability is the precision of repeated measurements within the same analytical run under the same operating conditions over a short interval of time. It is also termed intra-assay or intra-batch precision.
The ability of an instrument to measure the same input to the same value over a short period of time and over a narrow temperature range.
The total error that the measurement system will possibly add to the measurement. Components of repeatability include, but are not limited to, (depending on the system) resolution, timebase accuracy, trigger jitter, quantization noise, aliasing, interpolation and operator/environmental effects. Any result presented by a measurement system can be thought of as the sum of the actual jitter of the device "+" the repeatability of the measurement system.
The ability of a transducer to reproduce output readings when the same measurand value is applied to it consecutively, under the same conditions, and in the same direction. Repeatability is expressed as the maximum difference between output readings as a percent of full scale.
The ability to display the same value when a weight is placed on a scale more than one time. Often expressed as a standard deviation of 5 to 10 tests.

The ability of a device to return the same reading in successive measurements of the same signal. Usually written as a percentage of full scale, indicating the deviation between given readings or measurements taken under identical conditions
a system's ability to reproduce previous action/result or movement to a given position, time and time again. Repeatability is normally measured in either percentages or probability terms.
A measure of accuracy and stability for an instrument. The capability of an instrument to duplicate a previous answer to a previous experiment within a limited margin of error.
The ability of a transducer or readout instrument to reproduce readings when the same input is applied repeatedly.
The ability of an test instrument or test system to be able to provide the same result when a test is repeated with the same UUT. Poor repeatability is a problem that requires attention in any test system, and may arise from stray pick up, inconsistent contact between the UUT and the fixture, etc.

A measure of the repeat accuracy of a sensor and/or timer and/or control mechanism. Usually expressed as a distance or time.
Degree of deviation for a point approached repeatedly under identical operating conditions.
Repeatability is the variation in measurements taken by a single person or instrument on the same item and under the same conditions. A measurement may be said to be repeatable when this variation is smaller than some agreed limit.
