Detailed explanation-1: -There are many factors that come into play that affect the ability to repeat measurements including poor instrument quality, instruments out of calibration, inadequate methods of data collection and operator inefficiency or inexperience.
Detailed explanation-2: -Precision and repeatability can be seen easily from a table of results containing repeat measurements. If the repeat measurements are close together, the data is precise and repeatable.
Detailed explanation-3: -Repeatability is the variation that occurs when a person uses a gage to measure the same part repeatedly with the same measurement tool. When a gage is acceptable, the variation due to repeatability is small. For example, when we measure a washer over and over again, the values should group closely together.
