Answer 1

How long the dog runs without stopping

Step-by-step explanation:

The dependent or responding variable in an experiment is the variable that is dependent on the changes made to the independent variable. It is also the variable that is measured or recorded in an experiment.

In this experiment where a student tests the effect of caffeine on dogs. Three groups of dogs were used for the test and they received water, 10mg caffeine and 50mg caffeine respectively. The different level of caffeine used is tested by recording how long each dog runs without stopping. Hence, how long the dog runs without stopping is the DEPENDENT VARIABLE.
