Biology

Lesson Objective

By the end of this lesson, you will know how to read, interpret, and create accurate graphs.

​Why use graphs & tables?

Why use tables & graphs?

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

​

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

​Data Analysis

Why use tables & graphs?

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

​Data Analysis

​How do I construct good graphs?

How do I construct good 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)​

Data Analysis

How do I construct good graphs?

Graphs are useful because they help draw conclusions in scientific investigations.

​

Graphs are quick ways to see relationships between different variables.

​

Remember, D.R.Y M.I.X. (dependent variable = Y axis / independent variable = X axis)​
