Gage Repeatability and Reproducibility (GR&R) is a statistical method used to assess the measurement system variation of a process. The calculation of GR&R can be broken down into several steps: Step 1: Select the Sample Size The first step is to determine the sample size for the GR&R study....

Analysis:Statistical tools are used to quantify the data’s sources of variation (repeatability and reproducibility). Common statistical methods for Gage R&R analysis include Analysis of Variance (ANOVA) and the calculation of various statistics such as the percent of total variation due to repeatabilit...

Precision (repeatability and reproducibility) studies and sample-size calculation The growing choice of ophthalmic equipment has driven research into their precision. It is important that these studies are designed and apply appropriate statistical methods with the correct corresponding terminology. The ANOVA...
Reproducibility: the closeness of agreement between independent results obtained with the same method on identical test material but under different conditions (different operators, different apparatus, different laboratories, and/or after different intervals of time). The measure of reproducibility is the ...
