箱式图(Boxplot)是通过描述数据的5个常用统计数值(中位数、最大值、最小值、上四分位数和下四分位数)而展现数据分布的一种图形.其作为一种图形表示工具,可以直观地显示出数据分布的状态,迅速地剔除异常值,并能够比较多组数据之间的分布.作为探索性分析工具的箱式图,能提高数据处理的严谨性、准确性及可靠性,应在日常工作中加以推广应用.“,”Boxplot is a graph that shows the distribution of data by describing five commonly used statistics (median,maximum,minimum,upper quartiles,and lower quartiles) of the data.As a graphical representation tool,it could visually display the state of data distribution,quickly remove the outliers,and is able to compare the distribution of multiple sets of data.As a exploratory analysis tool,boxplot could improve the rigor of data processing,accuracy and reliability,and it should be generalized in daily work.
