本文件描述了单向和双向方差分析的必要步骤 （ANOVA）用于平衡设计中的固定效应模型。不平衡设计、随机效应和嵌套 本文档中不包括设计模式。 本文件提供了一些示例，通过拆分 观察到的总体差异分为不同部分。来自不同领域的几幅插图 重点介绍了方差分析的程序。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document describes the necessary steps of the one-way and two-way analyses of variance (ANOVA) for fixed effect models in balanced design. Unbalanced design, random effects and nested design patterns are not included in this document. This document provides examples to analyse the differences among group means by splitting the overall observed variance into different parts. Several illustrations from different fields with different emphasis suggest the procedure of the analysis of variance.All current amendments available at time of purchase are included with the purchase of this document.
