Statistical Quality Control
What are the three categories of statistical quality control?
Descriptive statistics, statistical process control (SPC), and acceptance sampling.
Statistics used to describe quality characteristics and relationships
Descriptive Statistics
A statistical tool that involves inspecting a random sample of the output from a process and deciding whether the process is producing products with characteristics that fall within a predetermined range.
Statistical Process Control (SPC)
The process of randomly inspecting a sample of goods and deciding whether to accept the entire lot based on the results.
Acceptance Sampling
A plan for acceptance sampling that specifies the parameters of the sampling process and the acceptance/rejection criteria.
Sampling Plan
Random causes of variation that cannot be identified and are typically attributed to variations in materials, workers, machines, and tools used in the production process.
Common Causes of Variation
Causes of variation that can be identified and are caused by poor material quality, poor employee workmanship, or machines in need of repair.
Assignable Causes of Variation

Six Sigma Quality
What are the five steps of six sigma?
Define, Measure, Analyze, Improve, and Contol (DMAIC)

Step One: Define
The six sigma step where you would measure the current performance of the process.
Step Two: Measure

Step Three: Analyze
The six sigma step where you would improve the process by eliminating the root causes of the quality problem.
Step Four: Improve
The six sigma step where you would control the process to ensure the improvements continue.
