Slide 3:Take a look at the bar graph on this screen. It shows the heights of six tall buildings in North America. Look at the y-axis of the graph and notice how the heights of the buildings are indicated in feet. The heights labeled on the y-axis increase by increments of 500 feet. Now notice how the names of the buildings are located along the x-axis of the graph. What “story” does this graph tell you? The graph provides information about six buildings in North America. It allows you to compare the heights of various buildings in relation to the others. Imagine trying to provide the same amount of information using words instead of a graph! Reading Bar Graphs


Slide 4:Interpreting Data Use this graph for the questions on the following page. A copy of this graph is also in your Power Point print off


Slide 5:What information can you get from the bar graph on the previous page? Try to answer the following questions using the bar graph. Interpreting Data


Slide 6:Line graphs are used to show a change in something over time. For example, you could use a line graph to show how temperatures changed in your area over the period of a year. Line graphs can also be used to show trends. You could use a line graph to show how consumption of soda changed in the period from 1950 to 1990 Reading Line Graphs


Slide 7:Pie charts, or circle graphs, are used to show data as parts of a whole. Use the pie chart on this screen to answer the following questions. Using Pie Charts
