SigmaXL was designed from the ground up to be a cost effective, powerful, but easy to use tool that enables users to measure, analyze, improve and control their service, transactional, and manufacturing processes. As an add-in to the already familiar Microsoft Excel, SigmaXL is ideal for Lean Six Sigma training or use in a college statistics course.
"I am happy to endorse the ANOM Charts introduced in SigmaXL Version 8. They are easy to use and accurately handle balanced and unbalanced data. We collaborated to extend Multiway Slicing to Binomial and Poisson and these are included in the Two-Way charts, where SigmaXL automatically recommends the Slice Charts when the interaction is significant."
Dr. Peter Wludyka, co-author of "The Analysis of Means: A Graphical Method for Comparing Means, Rates, And Proportions.
