下列哪个条形图可能表示所示扇形图中的数据?

Which one of the following bar graphs could represent the data from the circle graph shown?

答案:C
知识点:数据与图表解读比与比例
难度评级:660
解答:

两个涂色区域各占圆的四分之一,未涂色区域占一半。所以三个数量的比例是 14:14:12\tfrac14 : \tfrac14 : \tfrac12,即 1:1:21 : 1 : 2

相应条形图必须有两个涂色条高度相等,白色条高度正好是它们的两倍。只有选项 C 符合。

所以正确答案是 C

The two shaded regions are each one quarter of the circle, and the unshaded region is one half. So the three quantities are in the ratio 14:14:12,\tfrac14 : \tfrac14 : \tfrac12, or 1:1:2.1 : 1 : 2.

A matching bar graph must have the two shaded bars equal in height and the unshaded bar exactly twice as tall. Only one bar graph has two equal shaded bars with the white bar double their height.

Thus, the correct answer is C .
