ANOVA
overview 

Stat > ANOVA

Allows you to perform analysis of variance, test for equality of variances, and generate various plots.

Select one of the following commands:

One-Way - performs a one-way analysis of variance and multiple comparisons of means

Analysis of Means - displays an Analysis of Means chart for normal, binomial, or Poisson data

Balanced ANOVA - analyzes balanced ANOVA models with crossed or nested and fixed or random factors

General Linear Model - analyzes balanced or unbalanced ANOVA models with crossed or nested and fixed or random factors. You can include covariates and perform multiple comparisons of means.

Fully Nested ANOVA - analyzes fully nested ANOVA models and estimates variance components

General MANOVA - analyzes balanced or unbalanced MANOVA models with crossed or nested and fixed or random factors. You can also include covariates.

Test for Equal Variances - performs tests for the equality (also called the homogeneity) of the variances or the standard deviations of multiple populations.

Interval Plot -  produces graphs that show the variation of group means by plotting standard error bars or confidence intervals

Main Effects Plot -  generates a plot of response main effects with data means

Interactions Plot - generates an interaction plots (or matrix of plots) with data means
