Final answer:
Gage repeatability and reproducibility (GR&R) measures the consistency of a measurement system. Accuracy refers to how close a measured value is to the true value, while precision refers to the degree of agreement among repeated measurements. Measurement reliability assesses the consistency of a measure using qualitative or quantitative assessments.
Step-by-step explanation:
Repeatability and reproducibility: Gage repeatability and reproducibility (GR&R) is a measure used to assess the consistency and reliability of a measurement system. Repeatability refers to the degree of consistency in measurements made by the same operator using the same equipment and under the same conditions. Reproducibility refers to the degree of agreement in measurements made by different operators using the same equipment and under the same conditions.
Measurement accuracy and precision: Accuracy refers to how close a measured value is to the true or accepted value. It involves the presence of systematic errors, which are consistent and predictable deviations from the true value. Precision, on the other hand, refers to the degree of agreement or reproducibility among multiple measurements of the same quantity. It pertains to random errors, which are unpredictable fluctuations that cause measurements to scatter around the true value.
Measurement reliability: Measurement reliability refers to the consistency of a measure in producing the same results under the same circumstances. It can be assessed using qualitative or quantitative assessments. Qualitative assessments involve subjective judgments, while quantitative assessments involve statistical analyses to determine the level of agreement or consistency among measurements
