Kitchener, Ontario – SigmaXL Inc., a leading provider of user friendly Excel Add-ins for Statistical and Graphical analysis, announces the release of SigmaXL Version 7. New features include:

• “Traffic Light” Automatic Assumptions Check for t-Tests and ANOVA
  • A text report with color highlight gives the status of assumptions: Green (OK), Yellow (Warning) and Red (Serious Violation).
  • Normality, Robustness, Outliers, Randomness and Equal Variance are considered.
• Automatic Highlight for Pearson or Spearman Correlation
  • A yellow highlight is used to recommend significant Pearson or Spearman correlations.
  • The powerful Doornik-Hansen bivariate normality test is utilized and Pearson is highlighted if the data are bivariate normal, otherwise Spearman is highlighted.
• “Traffic Light” Attribute Measurement Systems Analysis (AMSA)
  • Binary, Ordinal and Nominal AMSA.
  • A Kappa color highlight is used to aid interpretation: Green (> .9), Yellow (.7-.9) and Red (< .7) for Binary and Nominal.
  • Kendall coefficients are highlighted for Ordinal.
  • A new Effectiveness Report treats each appraisal trial as an opportunity, rather than require agreement across all trials.
• Small Sample Exact Statistics for Chi-Square and Nonparametric Tests
  • Exact One-Way Chi-Square, Fisher’s Exact for Two-Way (Contingency) Tables and Exact Nonparametric Tests.
  • Monte Carlo Exact with Confidence Interval for tests that require excessive computation time.
  • Exact statistics are appropriate when the sample size is too small for a Chi-Square or Normal approximation to be valid – for example, a contingency table where more than 20% of the cells have an expected count of less than 5.

“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. Exact statistics for small samples are now available at a low cost where they are typically found only in advanced and expensive software packages,” said John Noguera, CTO, SigmaXL.

A free 30-day trial version is available for download from the SigmaXL website at: www.SigmaXL.com.
