A frequency distribution for qualitative data lists all categories and the number of elements that belong to each of the categories.

Data presented in the form of a frequency distribution are called ungrouped data.

The bar graph and the pie chart are two common types of graphs that are used to display quantitative data.

A graph made of bars whose heights represent the frequencies of respective categories

to construct a bar graph (bar chart), we mark the various categories on the vertical axis.

Bar charts can also be used to give a visual comparison of two or more groups.

When constructing a comparative bar graph we use the ............... rather than the .......... to construct the scale on the vertical axis

Pie charts are most effective for summarizing data sets when there are too many different categories

The class .......... is also called the class size.

The class ...... is given by the midpoint of the upper limit of one class and the lower limit of the next class.
