WebAdjusted P values are very different than Fisher's LSD P values. Note the huge difference: Adjusted P values correct for multiple comparisons; Fishers LSD test does not. The "exact" P values computed by the two methods, therefore, will give very different results and must be interpreted very differently. WebFeb 20, 2016 · 之前我一直都没有弄清楚卡方检验和Fisher exact test的区别。今天花时间专门整理、学习一下。卡方检验是一种用途很广的计数资料的假设检验方法。它属于非参数检验的范畴，主要是比较两个及两个以上样本率( 构成比）以及两个分类变量的关联性分析。其根本思想就是在于比较理论频数和实际频数 ...
WebWhen analyzing contingency tables with two rows and two columns, you can use either Fisher's exact test or the chi-square test. The Fisher's test is the best choice as it always gives the exact P value. The chi-square test is simpler to calculate but yields only an approximate P value. If a computer is doing the calculations, you should choose ... WebGraphPad Software has been dedicated to creating software exclusively for the international scientific community since 1984.
