Detailed explanation-1: -Ms. S set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. What is the dependent variable? Distance traveled by the ball.
Detailed explanation-2: -An independent variable is the variable you manipulate, control, or vary in an experimental study to explore its effects. It’s called “independent” because it’s not influenced by any other variables in the study. Independent variables are also called: Explanatory variables (they explain an event or outcome)
Detailed explanation-3: -An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
Detailed explanation-4: -The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores since that is what is being measured.
Detailed explanation-5: -The independent variable is the one that is changed by the scientist.
