|Day 1 – Statistics Primer
• Explain what variation in a work process is and why it is bad.
• Describe key techniques for measuring variation – visual display and mathematical.
• Identify key patterns of variation and explain what causes them
Lesson 1 (Introduction to Variation)
– What variation is and why it’s a problem in manufacturing
Lesson 2 ( Measuring Variation)
– Using a histogram to measure the variation in a process
Lesson 3 (Patterns of Variation)
– Types of patterns of variation, what they tell you, and what to do about them
Lesson 4 (Measures of Variation)
– Statistical measures of variation: Mean, range, and standard deviation
Lesson 5 (Normal Curve)
– Properties of the normal curve and the 68, 95, 99.7 rule
Lesson 6 (Stability)
– The importance of a stable process in manufacturing

• Contrast the difference between an “in-spec” process and a “capable process.”
• Identify and explain the three main measures of process capability.
Lesson 1 (What is Process Capability)
– What process capability means and why it’s important
