IV (Independent Variable): Dog food DV (Dependent Variable): The lifespan of the dog. Hypothesis: I can’t answer that for you.
Explanation: The independent variable is what is being manipulated or used to find something. In this case, it would be the dog food. The dependent variable is the result of what happens with the manipulation of the independent variable. So, the dependent variable would be the dog’s lifespan.
Unfortunately, I cannot answer the hypothesis for you because the hypothesis is what YOU think will happen.
