One means to display categorical data is with a bar chart. Several parallel bars are used, with the height of each bar proportional to the number of data in each category. For example, if one had 4 apples, 7 bananas, 5 guavas, 3 mangos, and 6 pears, the information could be displayed thus:

| ___ | | | ___ 5_| | | ___ | | | ___ | | | | | | | | | | | | | ___ | | | | | | | | | | | | | | | | | | | | | | | | |__|___|__|___|__|___|__|___|__|___|__ A B G M P Frequency of Fruit SelectionsNote that it is necessary to label the bar graph to convey information, in particular the number of fruit is indicated on the vertical axis. Alternatively, one could record the relative frequency of each type of fruit in which case the actual number of each type of fruit could not be read from the bar chart. A relative frequency bar chart would look essentially the same, but the vertical axis would be labelled differently:

| ___ | | | ___ 20%_| | | ___ | | | ___ | | | | | | | | | | | | | ___ | | 10%-| | | | | | | | | | | | | | | | | | | | | | |__|___|__|___|__|___|__|___|__|___|__ A B G M P Relative Frequency of Fruit Selections

This information can also be displayed in a pie chart, which by its manner of
display emphasizes relative freauencies (i.e., parts of the whole).

If one had a protractor (and the pie chart was accurately drawn), one could
determine 16% of the fruit were apples, 28% were bananas, etc.
Pie charts may also be labelled with more information including the actual counts.
