Final answer:
Measurement System Analysis (MSA) is used to identify the presence of special causes and ensure accurate and reliable measurement results.
Step-by-step explanation:
The correct purpose of Measurement System Analysis (MSA) is to identify the presence of special causes. MSA is a statistical process used to ensure that a measurement system is capable of producing accurate and reliable results. It involves assessing the measurement system's precision, accuracy, and stability, and identifying any sources of variation that could affect the measurements. By identifying special causes, MSA helps in identifying and addressing potential problems in the measurement process, leading to improved quality control and decision-making.
