问题18、如何用SPSS画方差分析的各单元均数图？
我们来看一个数据实例crf24（数据选择Kirk
1968第一版).
get file 'c:\crf24.sav'.
首先，我们先来看一个单元均数表以了解数据集中都有哪些变量。A 和 B可作为自变量，y看作因变量。
MEANS
TABLES=y by a by b.

现在我们来画单元均数图。
graph
/line(multiple) mean(y) by b by a.

如果你想对均数用符号标记，双击图形，选择"format"和 "interpolation",
再选择"straight".一定要选中"display markers"框。单击"apply"和"close"
，然后关闭图形编辑器。如果你想改换标记，再次双击图形，选择"format",然后选择"marker",
接着就可以选择你想要的标记和大小了。如果你想要不同组有不同的标记，双击图形，右侧组别标签的图例，然后选择（相当于单击）你想改变符号标记的那一组。接着，选择"format"和"marker",
然后选择需要的标记和大小。单击"apply"和"close" ，然后关闭图形编辑器。?

你也可以通过GLM作图。注意到在profile后括号里的第一个变量在x轴上。第二个变量代表变量"grouping"。
glm y by a b
/plot = profile(b*a).
