Difference between Repeatability vs Reproducibility in simple terms:
Repeatability
Variation that occurs when repeated measurements are made of the same item under absolutely identical conditions say, Same operator–Same setup–Same units–Same environmental conditions
If there are variation due to Gage or device
Reproducibility
Variation that results when different conditions are used to make the measurements say, :Different operators–Different setups–Different units–Different environmental conditions–Different measurement systems
Variation due to operators
