特别注意以下两种最可能考的情况:
j为0,即k%恰为整数,则结果恰为第个数
第个数与第个数相等,不用算也知道正是这两个数。
注意:我前面提到的Quartile也可用这种方法计算,
其中1st Quartile的k%=25%
2nd Quartile的k%=50%
3rd Quartile的k%=75%
计算结果一样。
例:
{1,3,4,5,6,7,8,9,19,29,39,49,59,69,79,80}共16个样本
30%:30%=4.5=4+0.5
第5个数+0.5第6个数=0.56+0.57=6.5
75%:1575%=11.25=11+0.25
第12个数+0.25第13个数=0.7559+0.2569=51.5
