Learning Objectives

  1. Recall the basic elements of a process control system.
  2. Define the process measures for variable data and attribute data.
  3. Interpret the graphical representation of data points in statistical distribution.
  4. Identify the elements of a control chart.
  5. Interpret the relationship between specification limits and control limits for process capability.
  6. Analyze process capability through process capability indices and process performance indices.
Statistical distribution in SPC represents the proximity of a data point to the mean value.
