Question

Simone is doing research with head injury victims who are in physical therapy. she believes that the addition of music to their physical therapy routine will enable them to better coordinate their motor skills. she randomizes the patients into two groups. group a will get the regular physical therapy sessions. group b will get the identical physical therapy sessions while listening to music. what is the independent variable?

Answer 1

The independent variable is the variable that is being changed within an experiment. In Simone's experiment, everything is being kept the same between the two groups except that one group will be listening to music during the PT sessions. The independent variable is therefore listening to music versus not listening to music.
