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.
