my science fair is that thing hoe does types of music affect your heart rate. the independent is they type of music dependant is the pulse so whats the control its due tueday help!!!Control variable??????????????????
The control variable would be someone's resting heart rate without the music.
Because
It is their heart rate in a controled environment.
Good luck.Control variable??????????????????
Right the control Variable is the thing that could affect the investigation but it is ALWAYS kept the same, so in your case it would be the person because if you changed the person the might a different regular pulse so it would be a unfair test.
Control, i think you need to use the same person to experiment on. Good luck, p.s I really dunno
