SPSS 单因素分析结果分析 求助高手回答

     这是我做的单因素分析的结果~（年龄段对乐观维度的影响）
     1. 如果方差齐次性检验<0.05，是不是不能做多重比较？如果一定要进行多重比较，如何处理方差齐次性的问题？
     2. 单因素分析中的显著性如果<0.05，是不是表明分析结果具有显著性？
     3. 如何再进一步进行多重比较？如何确定哪个年龄段的乐观维度得分较高？
     麻烦各路高手帮忙解决以上问题~~~小女子在此谢过~~~~~

Generally speaking, one-way anova is pretty robust to unequal variance, especially when the group size are equal.
For you case, the major concern here is the sample size of group 4 (>50) is too small compared to other groups. If I were you, I would combine group 3 (41-50) and group 4 (>50), run the one-way ANOVA again and don't care about the equal or unequal variance any more.

If you really care about the unequal variance and don't want to combine group 3 and 4, the following are two choices:
          1) In SPSS one-way ANOVA "Options", check "Brown-Forsythe" or "Welch". There two procedures are supposed to deal with one-way ANOVA with unequal variance
          2)Nonparametric Kruskal-Wallis ANOVA
