Graphing

The independent variable is the variable that can be controlled in an experiment. It is plotted on the X-axis.

The two types of relationships are inverse and direct. An example of an inverse relationship is: As you exercise more, your risk for heart disease decreases. An example of a direct relationship is: The higher your temperature, the higher your perspiration rate is.

The purpose of labeling the X-axis with units in a graph is to provide a clear understanding of the independent variable being measured or manipulated.
