This document contains 26 multiple choice questions related to statistical process control (SPC) and measurement system analysis (MSA). The questions cover topics such as the relationship between quality and variability, identifying attribute and variable data, uses of statistics, distinguishing common from special causes of variation, process capability indices, estimating rejection levels, and key concepts in MSA including errors, repeatability, reproducibility and requirements for an excellent measurement system.
