Making a good graph

Crafting a good graph is crucial for clear data presentation. Begin with a title formatted as "The dependence of (dependent variable) on (independent variable)." Ensure that the x-axis represents the independent variable, while the y-axis represents the dependent variable. Always label both axes clearly and include appropriate units. Utilize a line graph; do not connect the dots. Graph your data as large as possible within the available space. Avoid ambiguities—absence of titles, labels, and units leads to confusion. Follow these guidelines for a clear and informative visual representation.

Presentation Transcript

  1. Making a good graph

  2. STEP 1 • Always give your graph a title in the following form: "The dependence of (your dependent variable) on (your independent variable). 

  3. STEP 2 • The x-axis of a graph is always your independent variable and the y-axis is the dependent variable.

  4. Step 3 • Always label the x and y axes and give units.

  5. Always make a line graph

  6. Never, EVER, connect the dots on your graph!

  7. Make sure your data is graphed as large as possible in the space you've been given.

  8. There's no title.  What's it a graph of?  Who knows? • There are no labels on the x or y axis.  What are those numbers?  Who knows? • There are no units on the x or y axis.  Is this a graph of speed in miles per hour or a graph of temperature in Kelvins?  Who can tell? • Somebody played "connect the dots".  This should be a nice straight line which goes through the points or a curve that tends to follow them.
