- Identify the parts of a bar graph.
- Examine bar graphs presented in examples.
- Recognize that bar graphs can have vertical or horizontal scales.
- Interpret information from bar graphs presented in five interactive exercises.

- Describe the procedure for constructing a bar graph.
- Construct bar graphs for data presented in two exercises.

#### Data and Circle Graphs

The student will be able to:

- Define circle graph, sector and pie chart.
- Identify the parts of a circle graph.
- Examine circle graphs presented in examples.
- Recognize that a circle graph is easier to read when percents, not fractions, are used to label the data
- Explain why a circle graph is also called a pie chart.
- Recognize, if there are more than five or six categories in a set of data, then a circle graph is not a good choice for displaying that data.
- Recognize that circle graphs provide a visual presentation of the whole and its parts.
- Interpret information from circle graphs presented in five interactive exercises.

#### Constructing Circle Graphs

The student will be able to:

- Review the definition and purpose of a circle graphs.
- Examine the procedure for constructing a circle graph from a given set of data presented in table.
- Compute the values for the parts and the whole of the graph.
- Compute exactly what fraction or percent each item (part) represents.
- Compute the angle measure for each part of a circle graph.
- Draw and label the parts of a circle graph.
- Describe the procedure for constructing a circle graph.
- Recognize that circle graphs represent data visually in the same proportion as the numerical data given in a table.
- Construct circle graphs for data presented in two exercises.

#### Comparing Graphs

The student will be able to:

- Define visual data display.
- Describe the types of graphs learned in this unit and their uses.
- Compare and contrast different graphs.
- Recognize that circle graphs are best used to compare the parts of a whole.
- Recognize that bar graphs are used to compare facts.
- Recognize that a line graph is used to show changes over time.
