Categorical Data  The following table displays the sales figures and market share (percent of total sales) achieved by several major soft drink companies in That year a total of 9930 million cases of soft drink were sold.

Creating a Bar Graph Title your graph Label axes –Horizontal Axis is the categories –Vertical Axis can be Counts (Frequency) Proportions (Relative Frequency) Percents Scale your axes Draw vertical bars to represent counts, proportions, or percents

Creating a Pie Graph The most accurate way to create a pie graph is to use a computer. However pie graphs can be created using estimation, or by using a protractor and using the appropriate number of degrees to create the graph.

Bar Graphs show a bar that represents either the count, proportion, or percentage of each category. Bar graphs may or may not show all categories. Pie Graphs show how a “whole” divides into categories using either the proportion or percentage. To use a pie graph you must include all the categories that make up the whole.
