IASSC Certified Lean Six Sigma Green Belt (ICGB) — Question 23

After a Belt has put data through the smoothing process which chart would be used to look for trends in the data?

Answer options

• A. Moving Average Chart
• B. Multi-Vari Chart
• C. X bar Chart
• D. Pareto Chart

Correct answer: A

Explanation

The Moving Average Chart is specifically designed to identify trends by averaging data points over a specified period, making it ideal for smoothed data analysis. The other options, such as the Multi-Vari Chart and Pareto Chart, serve different purposes like displaying variations and prioritizing issues, which do not focus on trend analysis.
