Attribute ARR Test (MSA)

A test used in a Measurement System Analysis (MSA) that evaluates the trustworthiness of discrete (a.k.a. attribute or categorical) data according to three perspectives: 1) Accuracy, 2) Repeatability, and 3) Reproducibility. The common test is for single attributes that are discrete, but a Multiple Attribute ARR test can be run that allows for testing continuous (a.k.a. variable or numerical) data.
