IASSC Certified Lean Six Sigma Green Belt (ICGB) — Question 34

__________ Distributions occur when data comes from several sources that are supposed to be the same yet are not.

Answer options

• A. Skewed
• B. Bimodal
• C. Gaussian
• D. Tri-peaked

Correct answer: A

Explanation

The correct answer is A, as skewed distributions arise when data is not symmetrically distributed, often due to inconsistencies in data collection methods. Options B (bimodal), C (Gaussian), and D (tri-peaked) refer to specific types of distributions that do not necessarily imply the presence of multiple inconsistent data sources.
