What is the difference between independent and dependent variables?

dependent variable is what you are measuring e.g. independent variable is what you are changing e.g. type of water (distilled, tap, spring etc.)

this is how I remember the variables

I -----------------C ows D on't ----------M oo C are -----------S oftly

I ndependent --------C change D ependent ----------M measure C ontrol ----------------S ame (keep the same)
