Quizplus · Accepted Answer

In a histogram, the bars represent the class intervals of the data and their heights indicate the frequencies or counts within those intervals. The bar widths are usually all the same and do not convey any additional information. Option A is incorrect because the widths of the bars do not provide information about cumulative frequencies. Option B is also incorrect because the areas of the bars are not related to cumulative frequencies, but rather to the frequencies of data values within each class interval. Option D is incorrect because bar widths should not be related to the sample size, but rather to the size of the class intervals used in creating the histogram.
