简介
分布在数理统计中具有重要意义。分布是由阿贝(Abbe)于1863年⾸先提出的，后来由海尔墨特(Hermert)和现代统计学的奠基⼈之⼀的卡·⽪尔逊(C K·Pearson)分别于1875年和1900年推导出来，是统计学中的⼀个⾮常有⽤的著名分布。
定义
若n个相互独⽴的随机变量ξ?、ξ?、……、ξn，均服从标准正态分布（也称独⽴同分布于标准正态分布），则这n个服从标准正态分布的随机变量的平⽅和
构成⼀新的随机变量，其分布规律称为分布（chi-square distribution），
卡⽅分布
其中参数称为⾃由度，正如正态分布中均数或⽅差不同就是另⼀个正态分布⼀样，⾃由度不同就是另⼀个分布。记为或者（其中，为限制条件数）。
卡⽅分布是由正态分布构造⽽成的⼀个新的分布，当⾃由度很⼤时，分布近似为正态分布。
对于任意正整数x，⾃由度为的卡⽅分布是⼀个随机变量X的机率分布。
性质1) 分布在第⼀象限内，卡⽅值都是正值，呈正偏态（右偏态），随着参数
的增⼤，分布趋近于正态分布；卡⽅分布密度曲线下的⾯积都是1。2) 分布的均值与⽅差可以看出，随着⾃由度的增⼤，分布向正⽆穷⽅向延伸（因为均值越来越⼤），分布曲线也越来越低阔（因为⽅差越来越⼤）。3）不同的⾃由度决定不同的卡⽅分布，⾃由度越⼩，分布越偏斜。
4) 若互相独⽴，则：服从分布，⾃由度为
。5) 分布的均数为⾃由度，记为E( ) = 。
6) 分布的⽅差为2倍的⾃由度( )，记为D( ) = 。
概率表
分布不象正态分布那样将所有正态分布的查表都转化为标准正态分布去查，在分布中得对每个分布编制相应的概率值，这通过分布表中列出不同的⾃由度来表⽰，
卡⽅分布临界值表
在分布表中还需要如标准正态分布表中给出不同P 值⼀样，列出概率值，只不过这⾥的概率值是值以上分布曲线以下的概率。由于分布概率表中要列出很多分布的概率值，所以分布中所给出的P 值就不象标准正态分布中那样给出了400个不同的P 值，⽽只给出了有代表性的13个值，因此分布概率表的精度就更差，不过给出了常⽤的⼏个值，⾜够在实际中使⽤了。
