Quizplus · Accepted Answer

A bar chart is the best choice for depicting categorical data that have been summarized in a frequency distribution, relative frequency distribution, or percent frequency distribution. It is a graphical device that uses bars of equal width to represent the frequencies of categories. It is easy to read and interpret and is commonly used in statistical analysis. The other options may be appropriate for other types of data, but for categorical data summarized in this way, a bar chart is the most effective choice.
