Box plot (箱形图) 中 quartile (四分位数)原理,及python_matplotlib中Q1和Q3定义的不同,程序员大本营,技术文章内容聚合第一站。
形如其名,box plot中有一个方形的box,以及box两边延伸出两条whiskers;更重要的是它展示出一串数据的五个重要的元素,分别是:minimum,maximum,median(也被叫做second quartile,简称Q2),lower quartile(也被叫做first quartile,简称Q1)以及upper quartile(也被叫做third qua...
and the median divides this large box, the “interquartile range”, into two boxes, for the second and third quartiles. The whiskers span the first quartile, from the second quartile box down to the minimum, and the fourth quartile, from the third quartile box ...
Q1: First quartile = 64.5. Q2: Second quartile or median = 66. Q3: Third quartile = 70. To construct the box plot: Press 4:Plotsoff. Press ENTER. Arrow down and then use the right arrow key to go to the fifth picture, which is the box plot. Press ENTER. Arrow down to Xlist: ...

A. The range of the entire data set. B. The middle 50% of the data. C. The highest and lowest values in the data. D. The average value of the data. 相关知识点: 试题来源: 解析 B。解析:在箱线图中,四分位数间距代表数据的中间 50%。反馈...
(middle value), and the first and third quartiles. In fact, the median can also be called the second quartile. The box plot above is not a meaningless sample of the chart type: it shows the variation in quartiles determined by several different methods. These will be described in ...
The third quartile A quartileis one-fourth of the dataset. As such, the third quartile marks the end ofthe range in which three-fourths of the entries lie. Formula-wise, it's the median of the top half of the values. On the plot, it's the top side of the box. ...

boxchart(ydata) creates a box chart, or box plot, for each column of the matrix ydata. If ydata is a vector, then boxchart creates a single box chart. Each box chart displays the following information: the median, the lower and upper quartiles, any outliers (computed using the inter...
