Document Summary
Frequency distribution -- a table that displays frequencies, and sometimes relative and cumulative relative frequencies, for categories (categorical data), possible values (discrete numerical data), or class intervals (continuous data) Comparative bar chart -- two or more bars that use the same set of horizontal and vertical axes. Pie chart -- a graph of a frequency distribution for a categorical data set. Each category is represented by a slice of the pie, and the area of the slice is proportional to the corresponding frequency or relative frequency. Segmented bar graph -- a graph of a frequency distribution for a categorical data set. Each category is represented by a segment and a bar, and the area of the segment is proportional to the corresponding frequency or relative frequency.
