二．实验要求某企业在制定某商品的广告策略时，对不同广告形式在不同地区的广告效果（销售额）进行评估。
请以商品销售额为观测变量，以广告形式和地区为控制变量，通过单因素方差分析分别对广告形式、地区对销售额的影响进行分析。
三．实验内容分析广告形式对销售额的影响方法一1、打开数据，点击分析、比较均值，单因素。
将x3和x1分别添加到因变量列表和因子中。
2、点击两两比较，选LSD。
3、点击选项，选描述性和方差同质性检验。
4、点击确定，得到结果。
结论：方差齐性检验表中，显著性p=0.515>0.05，说明不同的广告形式与销售额是相关的，满足了方差分析的前提条件。
以结果中多重比较表做显著性分析，可以看出p<0.05时，,两个因素相比是显著的。
即针对报纸对于广播、宣传品、体验的显著性比较：报纸与广播相比不显著，两种广告形式对销售额的影响没什么差别；报纸相对于宣传品与体验，更显著，销售额更好；由于15.6667>1.3340，看出报纸对宣传品的显著性比报纸对广播的显著性大。
方法二：1、打开数据，点击分析、一般线性模型、单变量。
将X3和X1分别导入因变量和固定因子。
2、点击单变量中的两两比较,将X1导入两两比较检验，勾选LSD。
3、点击选项，将X1导入显示均值，勾选描述统计和方差齐性检验。
4、得出结果。
得到相同的结论。
分析地区形式对销售额的影响1、打开实验数据，点击菜单中“分析”->“一般线性模型”->“单变量”，将“销售额”作为“因变量”，“地区”作为“固定因子”：2、点击“两两比较”，将x2放到右边“两两比较检验”中，勾选“LSD”：3、点击“继续”，在“选项”面板中，将“（OVERRALL)”放到右边“显示均值”中去，并且勾选“描述统计”和“方差齐性检验”：4、点击模型，选择设定（自定义），类型改为主效应，吧x1，x2加到模型中。
5、点击“继续”，并且“确定”，得到结果：描述性统计量因变量: 销售额广告形式地区均值标准偏差N报纸1.00 71.5000 4.94975 22.00 66.0000 12.72792 23.00 79.50004.94975 24.00 71.5000 7.77817 25.00 70.50006.36396 26.00 74.0000 2.82843 27.00 73.0000
