Use Gage R&R Study (Nested) to assess the variation in your measurement system when every operator cannot measure all parts. If you cannot split a sample into four or more subsamples, …

The 3 operators measure the strength of each sample, two samples per part, for a total of 60 measurements. Because the measurements are nested within operator, the engineer performs …

Complete the following steps to interpret a nested gage R&R study. Key output includes variability estimates, and graphs of the measurements and measurement variability.

In a nested study, each part is unique to the operator; no two operators measure the same part. This study is called nested because one or more factors is nested under another factor and, …

Study variation Enter a constant to multiply by the standard deviation to estimate the variation in the measurements. The default multiplier is 6, which is the number of standard deviations that …

Two factors are nested when each level of one factor occurs with only one level of the other factor. For example, if two operators measure two different, but similar, sets of parts, parts are …

Find definitions and interpretation guidance for every statistic and graph that is provided with the nested gage R&R study.

Use Nested Gage R&R Study to assess the variation in your measurement system when every operator cannot measure all parts. For example, you have 3 operators and 15 parts.

Whenever operators measure unique parts, you have a nested design. If you need to include more factors than Operator and Part, have fixed factors, a mixture of crossed and nested …
