The exercise programs are the manipulated variable because the researcher assigned the participants to different programs, which allowed them to control and manipulate the independent variable. The amount of weight lost is the dependent variable because it is where change is observed and is influenced by the independent variable (exercise program). The measured variable would be the specific method used to measure the amount of weight lost (e.g. weighing scale).
