IASSC Certified Lean Six Sigma Black Belt (ICBB) — Question 82

The _____________ Distribution would be the most desirable for modeling the number of stitch defects in a portion of fabric.

Answer options

• A. Exponential
• B. Extended
• C. Poisson
• D. Weibull

Correct answer: C

Explanation

The Poisson Distribution is ideal for modeling the number of events, such as stitch defects, in a fixed interval of time or space, particularly when these events occur independently. The Exponential Distribution is used for the time between events, while Weibull is often used for reliability analysis, and Extended Distribution is not specifically relevant in this context.
