选项
A.Pareto Chart.

C.frequency polygon.
答案
A
解析
A is correct. A bar chart that orders categories by frequency in descending order and includes a line displaying cumulative relative frequency is called a Pareto Chart. A Pareto Chart is used to highlight dominant categories or the most important groups. B is incorrect because a grouped bar chart or clustered bar chart is used to present the frequency distribution of two categorical variables. C is incorrect because a frequency polygon is used to display frequency distributions.A是正确的。将类别结果按频率降序排列并包含显示累积相对频率的线条的柱状图称为帕累托图。帕累托图用于突出主要类别或最重要的群体。
