Graphical Analysis Charts

Bar Chart

This simple tool is used to show the differences between different groups of process data.

Discriminant Analysis Can Minimize Returned Products

It is cheaper to scrap production inside the facility than to be charged for a complete assembly found defective by the customer. Use discriminant analysis to separate those units that are likely to fail as soon as they come off the production line. 

Histogram

This simple tool is used to summarize and display process data in a graph.

Interpreting Anomalies Correctly Can Help Avoid Waste

Without the benefit of extensive project experience and strong statistical interpretive skills, a Green Belt or even Black Belt may improperly diagnose data anomalies, leading to poor decisions. Learning some quick analysis techniques can help.

Making Sense of Time Series Forecasting

Practitioners can benefit from understanding the logic behind the linear and quadratic trend models used in forecasting.

Understanding Scatter Diagrams and Correlation Analysis

Six Sigma scatter diagrams and their correlation analyses often debunk management myths. Many times executives assume that measures vary together when they do not or do not vary in concert with one another when they do. For better or worse, budget forecasts are based on these assumptions. Knowing which factors do and don't vary together improves forecasting accuracy. Improved forecasts can reduce decision risk.

Using Quadrant Plots to Improve Program Performance

When it comes to understanding discrete data, quadrant plots can provide visual clues for Six Sigma project team leaders as to where they should focus their efforts when measuring program performance.
