One-Way ANOVA

Analysis of Variance, or ANOVA, is the standard technique for quantifying and partitioning sample variance in experimental data. The ANOVA tools, both One-Way and Two-way, have been completely redesigned for Origin 7.0, making them more powerful and user-friendly. You can now perform analyses on non-contiguous datasets selected from any worksheet in the Origin project file. Three new means comparison tests (Bonferroni, Sheffé, and Tukey) have been added to One-Way ANOVA, as well as Levene and Brown-Forsythe tests for equal variance. Actual power can be computed for a specified alpha level, and Hypothetical power can be computed for varying sample sizes. What's more, tests can be conducted, data selected and other analysis details changed without having to close the ANOVA dialog box, thereby saving you valuable time.
