Correct Sample Size for Attribute Gage R&R (Good / Bad parts)

★ ★ ★ ★ ☆

7/29/2013 · A common standard for a Continuous GR&R study is to use 10 parts, measured by 3 different people, 3 times each, giving you a total of 90 results. For Attribute data GR&R studies more data is required (Due to Attribute data having less resolution) therefore at least 20 parts should be assessed at least 3 times by each appraiser giving 180 results.

In science and research, an attribute is a characteristic of an object (person, thing, etc.). Attributes are closely related to variables. A variable is a logical set of attributes. Variables can "vary" - for example, be high or low. How high, or how low, is determined by the value of the attribute (and in fact, an attribute could be just the word "low" or "high").
