Kitchener, Ontario February 27, 2017—SigmaXL Inc., a leading provider of user friendly Excel Add-ins for Statistical and Graphical analysis, announces the release of SigmaXL Version 8.

“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.  Our slogan for Version 8 is Multiple Comparisons Made Easy,” said John Noguera, CTO, SigmaXL.

Dr. Peter Wludyka, co-author of the book, The Analysis of Means: A Graphical Method for Comparing Means, Rates, and Proportions, “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 Slice Charts when the interaction is significant.”A free 30-day trial version is available for download from the SigmaXL website at:
