第0个Quartile实际为通常所说的最小值
第1个Quartile
第2个Quartile实际为通常所说的中分位数
第3个Quartile
第4个Quartile实际为通常所说的最大值
我想大家除了对1st、3rd Quartile不了解外,对其他几个统计量的求法都是比较熟悉的了,而求1st、3rd是比较麻烦的,下面以求1rd为例:
设样本数为n,可以按下列步骤求1st Quartile:
将n个数从小到大排列,求/4,设商为i,余数为j
则可求得1st Quartile为:/4+j/4
例:
1.设序列为{5},只有一个样本则:/4 商0,余数0
1st=第1个数4/4+第2个数0/4=5
