The document discusses frequency tables and bar graphs. It provides an example of a frequency table showing the results of a student survey about favorite foods. It then shows how to construct a vertical bar graph using the frequency table data, with instructions on labeling the axes, choosing an appropriate scale, and drawing bars proportional to each food's frequency.

2. The frequency of a data value is equal
to the number of times that the value
occurs
 A Frequency Table arranges data values
in order from least to greatest with their
corresponding frequency

3. 
If given this data
Student survey
What is your favorite food?

would look like this

4. Definition: A Graph consisting of vertical
or horizontal bars that proportionally
represent a set of data
 Use: to compare and display data


Horizontal

5. Make a title for your graph
 Label each axis
 Determine a scale for the X and Y axis

Frequency

Types of Food

6. Labeling the Y-axis: Because the frequency
of the data is between 0 and 8, a good
scale for this graph would be 0-8
 Labeling the X-axis: use each option as a
category

