In a frequency distribution, the absolute frequency measure
选项:
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解释:
B is correct. In a frequency distribution, the absolute frequency, or simply the raw frequency, is the actual number of observations counted for each unique value of the variable. A is incorrect because the relative frequency, which is calculated as the absolute frequency of each unique value of the variable divided by the total number of observations, presents the absolute frequencies in terms of percentages. C is incorrect because the relative (not absolute) frequency provides a normalized measure of the distribution of the data, allowing comparisons between datasets with different numbers of total observations.
