请大家帮忙看看那，我是入门。。

我的作业是要把 DEMO_F 和SMQ_F 这两个data 做数据处理。。谢谢大家~~我不太确定我做的对不对，让大家帮忙看看
分别作 PROC CONTENTS, FREQUENCEY, MERGE, CREATE NEW VARIABLE, CREATE A NEW VARIABLE USING EXISTING DATA,
TWO-VARIABLES T-TEST

你有没有运行一下？

Cactus.hui 发表于 2012-12-20 14:27

我没有这个软件。。呜呜呜

楼主改完了要把结果共享下啊

糖姑娘。 发表于 2014-1-25 09:40

我们程序都有现成的，一般不怎么临时编
