sorry i put my question in the wrong place. ok my question is can you tell me if i did this correctly. my experiment was about how can you tell if the person is lying by his body language. will my independent variable be when i interview a person on a dim light while i interview others on a normal light. then my dependent variable will be what happen or what change on the answers of all that was interviewed. the controlled variable willbe the questions to each person will be the same. is this right? because this is how i understand it. please help i really need the answer badly! thanks for all your help !!!!!
