老师 在练习题第三题 In a frequency distribution, the absolute frequency measure: A represents the percentages of each unique value of the variable. B represents the actual number of observations counted for each unique value of the variable. C allows for comparisons between datasets with different numbers of total observations. 如果我把题目换成tree map 的作用，是否C是一个对于tree map的合理描述呀。
