Awww, thats so easy! Just keep studying!How can I remember the independent variable, dependent v., control group,constants?
Mnemonic that might help: IV - what *I* change. If you know that one, you would then know that DV is what changed as a result of the variable you changed (IV)


For control group and constants, just remember they don't change. The control group is there so you can compare it with what you experimented on. A constant is not a variable, so it doesn't change. I hope that helped.
