What would be the control, dependent variable, and independent variable?
This is the hypothesis "Would video games affect your heart rate? My brother doesn't trust my answers so I need someone to prove me right!|||Independent variable is the presence or absence of the computer game
The dependent variable is the change in heart rate
The constants are the conditions under which the test is carried out (same time of day, same length of exposure to the game or to no game) same batch of volunteers, each tested with and without the game. Same game used in all tests
Do our lists match ??
