如何用spss软件做单因素方差分析！下面两个题最好说出步骤与分析的结果！急求高手回答。

1. Using the grad_hsb_data set,

1) Draw the bar graph that shows mean WRTG scores with standard error bars as a function of RACE.

2) Run a single-factor ANOVA using RACE as the independent variable and WRTG as the dependent variable.
3) Conduct a post-hoc test to determine which pairs of RACE are different? Describe your post-hoc test results.
4) Following the APA publication guidelines, write the results section based on the analyses performed for 1)-3) above.
2. (Use the grad_hsb_data set)
Suppose you established the following specific hypotheses about differences among races in advance, conduct planned contrasts using WRTG as the dependent variable.
1) Difference between BLACK and WHITE.
2) Difference between WHITE and non-WHITE.
3) Difference between HISPANIC/BLACK and ASIAN/WHITE.
Describe the results of your planned comparisons.

4) Difference between WHITE and HISPANIC/BLACK.

Answer 1

点菜单 analyze - compare means - ony way anove
出选项 dependent list 选A 、factor 选B 研究A的不同对B是否有差异
出分析后 第一个表 是 各组方差齐性检验 若 sig>0.05 方差一致无差异
第二个表 组间方差分析 若sig<0.05 则有差异反之无差异
第三个表 均值配组比较 用于看 各两两之间的是否有差异 <0.05的两组就存在差异
