箱线图(boxplot)简介与举例 Tukey)发明的。它由五个数值点组成:最小值(min),下四分位数(Q1),中位数(median),上四分位数(Q3),最大值(max)。也可以往盒图里面加入平均值(mean)。如上图。下四分位数、中位数、上四分位数组成一个“带有隔间的盒子”。上四分位数到最大值之间建立一条延伸线,这个延...
In this post, we will learn how to draw a line connecting the mean (or median) values in a boxplot in R using ggplot2. Connecting mean or median values in each group i.e. each box in boxplot can help easily see the pattern across different groups. The basic idea in making a boxp...
I am encountering some issues while trying to create a box plot with R. The plot loads on the screen, i..e no problems with libraries; however, the mean and median are completely wrong. For the far left box, the mean is supposed to be 4.3, yet, as you can see it is clo...
The solid box shows the range of the middle 50% of the Cqvalues for the target or the sample. The horizontal black bar shows the median Cqvalue. The black circle shows the mean Cqvalue. The ends of the vertical lines (or "whiskers") show the maximum and minimum Cqvalues, unless outli...

The letter-value plot is motivated by the fact that when more data is collected, more stable estimates of the tails can be made. In addition, more data points mean that more of them will be labeled as outliers, whether legitimately or not. While the letter-value plot is still somewhat la...
When to Use a BoxplotA boxplot may help when you need more information from a data set/distribution than just the measures of central tendency (mean, median and mode). Boxplots can illustrate the variability or dispersion of all data points present within a set, giving a good indication ...
