Six Sigma Green Belt Certification Practice Exam

Question: 1 / 400

Positional, cyclical, and temporal variations are most commonly analyzed in which chart type?

SPC charts

Multi-vari charts

The focus on analyzing positional, cyclical, and temporal variations aligns most closely with multi-vari charts. These charts are specifically designed to display and evaluate the relationships among multiple factors and their variations over time. By visualizing data across different dimensions, multi-vari charts help identify how variations occur in relation to different conditions or groupings.

In contrast, SPC charts are predominantly used for monitoring process stability and control over time, while cause and effect diagrams are geared towards identifying and analyzing the potential causes of a problem rather than variations in data over time. Run charts, although they do display data trends over time, do not specifically focus on the comprehensive analysis of variations by other factors like positional or cyclical aspects. Thus, multi-vari charts are the best choice for this type of analysis.
