Statistical Analysis
Statistical software simplifies analysis but requires understanding of which tests to use in different situations
Tools such as Hypothesis Testing, Correlation and Regression Analysis, and Design of Experiments help draw conclusions and understand relationships between variables
-
Root Cause Verification
Verification methods include statistical analysis, experiments, data analysis, and process mapping
-
Once possible root causes are identified, they must be verified
