- Identify the parts of a line graph.
- Examine line graphs presented in examples.
- Interpret information from line graphs presented in exercises.
Constructing Line Graphs
The student will be able to:
- Define range, horizontal scale and vertical scale.
- Examine the procedure for constructing a line graph from a given set of data.
- Describe the procedure for constructing a line graph.
- Construct line graphs for data presented in exercises.
Data and Bar Graphs
The student will be able to:
- Define bar graph, grid line and categories.
- 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 exercises.
Constructing Bar Graphs
The student will be able to:
- Define bar, bar length and bar height.
- Examine the procedure for constructing a bar graph from a given set of data.
- Describe the procedure for constructing a bar graph.
- Construct bar graphs for data presented in 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 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 that the area of each sector is in the same proportion to the whole circle as the number for each item in the table is to the total of all items.
- Construct circle graphs for data presented in 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.
- Determine which type of graph is appropriate for representing a given set of data presented in exercises.
- Connect graphs to data found in the real world.
Practice Exercises
The student will be able to:
- Interpret and analyze graphs to determine what information is given.
- Complete exercises by applying data and graph concepts.
- Self-assess knowledge and skills acquired from this unit.
Challenge Exercises
The student will be able to:
- Interpret and analyze graphs to determine what information is given.
- Compare a set of graphs that each represent the same data to determine which one shows all of these facts correctly.
- Determine which type of graph is appropriate for representing a given set of data presented in each of three exercises.
- Determine what is wrong with a given graph presented in each of four exercises.
- Develop problem-solving skills.
Solutions
The student will be able to:
- Examine the answer for each exercise presented in this unit.
- Examine the graphs created as a possible solution to exercises presented in this unit.
- Recognize that graphs created will vary depending on the scales used.
- Compare answers and solutions to those completed.
- Identify and evaluate incorrect answers.
- Reconstruct and label graphs that did not accurately represent the data present in exercises.
- Identify areas of strength and weakness.
- Decide which concepts and procedures need to be reviewed from this unit.
