2检验是一种非常重要的，用途非常广 泛的假设检验方法。用以检验多个率（或构成比）之间差异是否具有统计学意义，当然也适合于两组比较。2检验来源于2分布，2分布是一种非常 重要的连续性分布。K.Pearson 2分布（chi-squaredistribution）0.50.40.3 f()2(...
（chi-squaredistributiontable），其基本推导及内容为：1、计数资料对某种理论的符合程度K设0为实际次数，T为理论次数∑（0-T）＝0i=1n、为所有情况之总体数；K为总情况数。生物统计学 例：检查F2代400株中红花281株、白花119株、理论为300株、100株。∑＝(300-281)+(100-119)＝0无意义。b、改进K∑（0...
1899年Karl pearson完善了X2检验法和X2值的抽样分布表(chi-square distribution table),其基本推导及内容为: 1、计数资料对某种理论的符合程度 K 设0为实际次数,T为理论次数 ∑(0-T)= 0 i=1 n、为所有情况之总体数; K为总情况数。 例:检查F2代400株中红花281株、白花119株、理论为300株、100株。 ∑...

该表计算的是:P(X<=x)【某个数落在某个[-@,x]】的概率。也就是下面阴影图形所示的面积: 如果x=1.96.则将1.96拆分为1.9和0.06.横轴1.9和纵轴0.06的交汇处:0.975.就是x<=1.96的概率。 也就是说,标准正态分布图形与x=a所围面积等于x<=a(某个值落在组数据的某个区间的)的概率。
