Document Summary
A graph of a frequency distribution with the horizontal axis showing the classes, the vertical axis showing the frequency count, and (for equal class widths) the rectangles having a height equal to the frequency in each class ogive. The graphical representation of the cumulative relative frequency. A line is connected to points plotted above the upper limit of each class at a height corresponding to the cumulative relative frequency bar chart. A graphical representation of a categorical data set in which a rectangle or bar is drawn over each category or class. The length or height of each bar represents the frequency or percentage of observations or some other measure associated with the category. The bars may all be the same color or they may be different colors depicting different categories. Additionally, multiple variables can be graphed on the same bar chart pie chart. A graph in the shape of a circle.
