Create a Graph is an interactive, online tool that allows users to make and interpret a variety of graphs, including bar, line, pie, area, and xy type graphs. Sponsored by the National Center for Educational Statistics (NCES), this site provides an easy way to create graphs which can then be printed or saved.

Activity - Use Create A Graph for Generating and Testing Hypotheses

1. Go to Create A Graph.
2. Using your own data set, select the most appropriate type of chart to use. For example, if you are looking at population data for a given city over time, you would probably want to use a line chart. If you are using data that compares height to age, would use a bar chart. If you want to see the relationship between latitude and average temperature, an XY scatterplot would be appropriate. See the following examples with questions students might use to test the data and make predictions:

How has the population of Philadelphia changed over the past 200 years?
What factors may have influenced change in population at certain times?

Do age and height increase proportionately from age 0 to 3?
What would be an indicator of abnormal growth?

Is temperature affected by how close you live to the equator?
Do cities located along similar latitudes have the same temperature?

3. Click on the following tabs as you create your chart:

Design - appearance of the graph 2D/3D, color, shading

Data - title of your chart, XY axis labels if required, and your data here

Labels - axis, title and data series

Preview - what your chart looks like as you work on it

Click on the Print/Save tab and save your chart as a .jpg file.

4. Upload the image of your chart to your Generating & Testing Hypotheses page. Develop two or three questions related to your chart that would help students generate or test a hypothesis. Share ways this tool is applicable to your curriculum.

Extension

Use the following instructions from Create A Graph to make a chart showing your school's student population.

Click on your state and then click on the letter your city begins with. Find your city and click on it. Then scroll through the list of schools until you find yours. Click on your school.

Look at Enrollment by race/ethnicity and see how it is represented in a pie chart.

Write down the information under Enrollment by Grade, recording how many students are in each grade.

Then go to the Create-A-Graph and use the information you recorded to make your own graph showing how many students are in each grade at your school. What is the best graph to use? Try using different kinds of graphs.

Allows users to create charts online quickly. Create bar charts, line charts or pie charts by simply pasting your data in the chart data area and hitting the create chart button.
