Ceramic component strength

An engineer wants to monitor the impact strength of ceramic components. The engineer randomly selects 30 samples that represent the expected range of the process variation and gives 10 random samples to 3 randomly selected operators. The 3 operators measure the temperature of the 10 different samples twice, for a total of 60 measurements. Each part (sample) is unique to operator; no 2 operators measured the same part.

You can use this data to demonstrate Nested Gage R&R Study.

Worksheet column Description
Part The part identifier: 1–30
Operator The operator who measured the part: 1, 2, or 3
Response The strength of the part
