SSC MTS EXAM

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 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-3: -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-4: -The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only ONE independent variable. As the scientist changes the independent variable, he or she records the data that they collect.
