How to read/write scientific graphs

• Tables and graphs allow information to be clearly viewed and interpreted.

​

• ​Graphs should be based on information recorded in the data table(s).

• In Biology, you will spend much time creating bar graphs and line graphs.

​Good graphs contain

• Labels on both the X and Y axes;

• A title (Use the label names for the X & Y to create your title.)

• Color

• Clear data points

• A key (if necessary)​
