MSA stands for Measurement Statistical Analysis. It determines whether a measuring system can precisely measure using statistical tools such as gage R&R (repeatability and reproducibility) tests. MSA gives confidence to data collection methods to verify collective data integrity and evaluates the measurement techniques, test methods, and data collection practices. MSA is characterized in five ways, Stability is the capacity of a measurement system to give the same values over the time measuring the same sample. Bias measures the distance between the sample's average value and actual value. Linearity is a measure of the consistency of Bias. Repeatability  Reproducibility
