How to Make a Hypothesis With Two Variables
The scientific method was one of the great contributions of the Enlightenment, and it remains a bedrock methodological rule of scientific study today. In the scientific method, empirical tests are administered to evaluate a hypothesis. An independent and a dependent variable are formulated to ascertain the veracity of said hypothesis.

1
Determine what, exactly, you want to find out. This will guide the development of your hypothesis.
-
2
Make a prediction as to the outcome of the experiment or study. This is the hypothesis. For example, in an imaginary study of a new cancer drug, you may hypothesize that X drug will reduce mortality in cancer patients.

3
Establish an independent variable. This is the presumed cause that will be tested for. In the given example, the patients administered the experimental drug X will constitute the independent variable group.
-
4
Determine the dependent variable. The dependent variable is the factor that the independent variable acts on. In this case, the dependent variable would be cancer mortality rates.
