1) broken line picture of frequency
频率折线图
2) frequency density polygon
频率密度折线图
1.
Directed against the limits of common histogram,this paper introduces the concept of frequency density,improves the common histogram by frequency density histogram,goes a step further,and meliorates the frequency polygon by frequency density polygon,which is applied to explaining probability density function.
文章针对一般直方图的局限,引入频率密度的概念,提出改进的频率密度直方图,进而对折线图进行改进,得到频率密度折线图,以此作为概率密度的图解。
4) cumulative frequency polygon
累计频数(或频率)折线
5) reduced frequency
折合频率
1.
