Categorical Data (Qualitative Data): data that fits into exactly one of several different groups or categories.• Some data (area codes) are numbers but
act as labels which would be put into a category.
Quantitative Data (Numerical Data):• Data for which each piece can be placed on
a numerical scale & compared.

Bar Graph: Displays categorical data using either horizontal or vertical bars on a graph.• Height or Length of each bar indicates
the value of the category.
Circle Graph (pie chart): Displays categorical using sectors or "wedges" of a circle.• Shows how parts of the whole relate to
the whole & how parts of the whole relate to the other parts.
• Shows percentages of the whole.
