题目
A heat map is best suited for visualizing the:
选项
A.frequency of textual data.
B.degree of correlation between different variables.
C.shape, center, and spread of the distribution of numerical data.
答案
B
解析
B is correct. A heat map is commonly used for visualizing the degree of correlation between different variables. A is incorrect because a word cloud, or tag cloud, not a heat map, is a visual device for representing textual data with the size of each distinct word being proportional to the frequency with which it appears in the given text. C is incorrect because a histogram, not a heat map, depicts the shape, center, and spread of the distribution of numerical data. B是正确的，热力图，通常用于显示不同变量之间的关联程度。A是不正确的，因为词云是表示文本数据的可视化设备，每个不同单词的大小与它在给定文本中出现的频率成比例。C是不正确的，直方图描述了数值数据分布的形状、中心和分布。
