Question

For quality control purposes, which of the following metrics would need to be determined when asked to find the control limit for individual ranges and various sources of variation?

A) Equipment Variation (EV), Appraiser Variation (AV), Repeatability, Reproducibility (R)
B) Process Variation (PV), Systematic Variation (SV), Operator Variation (OV)
C) Random Variation (RV), Environmental Variation (EV), Product Variation (PV)
D) Measurement Variation (MV), Procedural Variation (PV), Systematic Variation (SV)

Answer 1

In quality control, the metrics needed to determine the control limit for individual ranges and sources of variation include Equipment Variation, Appraiser Variation, and Repeatability/Reproducibility.

Step-by-step explanation:

In quality control, when determining the control limit for individual ranges and various sources of variation, the relevant metrics are:

• Equipment Variation (EV): Differences in measurement due to variations in the instruments used.
• Appraiser Variation (AV): Differences in measurement due to variations between people conducting the measurements.
• Repeatability, Reproducibility (R): Variability resulting from the interaction between the appraiser and the part being measured.

So, the correct answer is A) Equipment Variation (EV), Appraiser Variation (AV), Repeatability, Reproducibility (R).
