SigmaXL - Powerful Statistical and Graphical Analysis

SigmaXL is a leading provider of user friendly Excel add-in tools for statistical and graphical analysis. Our flagship product, SigmaXL was designed from the ground up to be cost-effective, powerful, and easy to use. It allows users to measure, analyze, improve, and control their service, transactional and manufacturing process. As an add-in to the already familiar Microsoft Excel, SigmaXL is ideal for Six Sigma training and is used by leading consultants. It is rapidly becoming the tool of choice for Six Sigma professionals.

SigmaXL is a fraction of the cost of any major statistical product, yet it has all the statistical and graphical functionality most people need.

 

 

 

 

SigmaXL includes Lean and DMAIC Templates and a Control Chart Selection tool to simplify the selection of SPC Charts.

 

 

 

 

An example of user friendliness is the Two Sample Comparison Test, which automatically tests for normality, equal variance, means, and medians. It also provides rule-based yellow highlighting to aid the user's interpretation of the output. Low p-values are highlighted in red indicating that the results are significant.

You can design experiments and "view power analysis" as you design! This allows you to readily see the trade off between the cost of experimental runs/replicates and the corresponding statistical power - before you finalize the design.

 

SigmaXL is the perfect tool for Six Sigma® Green Belts, Black Belts, Quality and Business Professionals, Engineers, and Managers.

SigmaXL V7 is compatible with Excel 2007-2013 and can accommodate more than 1 million rows of data. Included are additional Six Sigma DMAIC templates, a DMAIC Menu option and a Control Chart Selection Tool to simplify the selection of SPC charts
