This is a graph that shows a girl walking her dog. 3 Communicating with GraphsPowerPoint Presentation: A Visual Display Communicating with Graphs The horizontal axis, or the x -axis, measures time. Time is the independent variable because as it changes, it affects the measure of another variable. 3PowerPoint Presentation: Line Graphs A line graph can show any relationship where the dependent variable changes due to a change in the independent variable. Communicating with Graphs 3PowerPoint Presentation: Line Graphs Line graphs often show how a relationship between variables changes over time. Communicating with Graphs 3PowerPoint Presentation: Constructing Line Graphs The most important factor in making a line graph is always using the x -axis for the independent variable. Communicating with Graphs The y -axis always is used for the dependent variable. 3PowerPoint Presentation: Bar Graphs A bar graph is useful for comparing information collected by counting. For example, suppose you counted the number of students in every classroom in your school on a particular day and organized your data in a table. Communicating with Graphs 3PowerPoint Presentation: Bar Graphs Communicating with Graphs As on a line graph, the independent variable is plotted on the x- axis and the dependent variable is plotted on the y - axis. 3PowerPoint Presentation: Circle Graphs A circle graph, or pie graph, is used to show how some fixed quantity is broken down into parts. Communicating with Graphs The circular pie represents the total. The slices represent the parts and usually are represented as percentages of the total. 3PowerPoint Presentation: Circle Graphs Communicating with Graphs To create a circle graph, you start with the total of what you are analyzing. This graph starts with 72 buildings in the neighborhood. 3PowerPoint Presentation: Circle Graphs Communicating with Graphs For each type of heating fuel, you divide the number of buildings using each type of fuel by the total (72). 3PowerPoint Presentation: Circle Graphs Communicating with Graphs You then multiply that decimal by 360 to determine the angle that the decimal makes in the circle. Eighteen buildings use steam. Therefore, 18 72 x 360 = 90 on the circle graph. You then would measure 90 on the circle with your protractor to show 25 percent. 3Review Question #1: Review Question #1 Which graph would be appropriate for showing the growth rate of a plant for six weeks? Bar graph Circle graph Line graphQuestion 1 Answer: Question 1 Answer The correct answer is C. Line graphs are appropriate for showing changes over time.Review Question #2: Review Question #2 When drawing a bar or line graph, where should you put the independent variable and the dependent variable?Question 2 Answer: Question 2 Answer The independent variable always goes on the x-axis, and the dependent variable goes on the y-axis.
