Investigations Involving Temperature and Volume Preview CT-STEM

Interpreting the Graph

You created a graph of volume versus temperature on the previous page. We are going to use that graph to determine the relationship between volume and temperature. First we will go over the different types of data relationships.

If you observe your independent variable increasing as your dependent variable increases (or if one variable decreases as the other decreases) your variables are said to have a direct relationship. A graph of two variables (A and B) with a direct relationship is shown below.

If you observe your independent variable increasing as your dependent variable decreases (or if the independent variable decreases as the dependent variable increases) your variables are said to have a inverse relationship. A graph of two variables (A and B) with an inverse relationship is shown below.
