[求助]分类资料的相关分析
** bcl-2
** * + -
p53 + 11 5

因只算了阳性率,未将结果进行分级,用SPSS行四格表分析,得卡方=4.62 p=0.03 有显著性差异,
spss分析结果如下:
Chi-Square Tests
Value df Asymp. Sig. (2-sided) Exact Sig. (2-sided) Exact Sig. (1-sided)
Pearson Chi-Square 4.627(b) 1 .031
Continuity Correction(a) 3.359 1 .067
Likelihood Ratio 4.713 1 .030
Fisher's Exact Test .055 .033
Linear-by-Linear Association 4.517 1 .034
N of Valid Cases 42
a Computed only for a 2x2 table
b 0 cells (.0%) have expected count less than 5. The minimum expected count is 7.62.

Measure of Agreement Kappa .326 .144 2.151 .031

a Not assuming the null hypothesis.
b Using the asymptotic standard error assuming the null hypothesis.
c Based on normal approximation.
请问,1.本资料能否如此行相关分析?
2.我报告结果为有相关,且r=0.332,如何对r行显著性检验和报告p值? 是否spss已报告结果为sr=0.145 p=0.032 呵呵,不要骂我菜了
3. 本资料符合x2检验的条件,但同时Fisher's Exact Test显示的结果为p=0.055, 究竟以那个为准?
4. 能否计算Kappa值说明两指标表达的一致性?它和r的主要意义区别在哪?
非常感谢!
