Pedro designs an experiment to test whether drinking a protein shake after weightlifting increases muscle development. The independent variable in his experiment is the protein shake
Indicate whether this statement is true or false.
Answer: True
Rationale: The independent variable is the variable that the experimenter manipulates to distinguish between the groups. In this experiment, one group of participants would receive the protein drink while the other would not. Pedro would then measure the muscle development (dependent variable) in each group to determine if the independent variable had an effect.
