Do control variable and dependent variable mean the same thing?

I am looking at a study and it talks about the control variables. Specifically, it says that the control variables are gender, race and education as variables to how much television a child watches.|||the control variable is actually the independent variable. it's the variable that you as an experimenter can manipulate (ie. you can choose to look at only women, only Caucasians, only preschoolers, etc etc). How many hours of television a child watches is the dependent variable and you as an experimenter can't manipulate that (well, i guess you can by switching the tv off but that would defeat the point of the actual study) |||Control variable is just another way of saying an independent variable,


The dependent variable is dependent on the independant variable,





so if you have y=3x+6





x is the dependent variable, as if you make y=1 then 1*3+6=9





so x depends on the value of y|||Above answer is true upto some extent but i think y is dependent on x value





if x=1 then y=3*1+6 = 9


else if x=2 then y=3*2+6 = 12





other wise if are calculating x based in y then x will be dependent and y will be controlling:





ex: x=(y-6)/3








and |||In this instance, the control variable is the independent variable(s).


The dependent variable is the time spent by the child.|||Control variables are something that remains fixed and you cannot change.





Dependant variables are ones which you can change and they are the ones which are varied in order for you to draw conculsions.





For example, you cannot change someone's gender, race or education (at least not without a great deal of work) and therefore they are control variables as they remained fixed.





Things like how much TV a child watches can be changed and therefore is a dependant variable. Not all children will watch the same amount of TV even if they their control variables are similar or the same and therefore conclusions can be drawn.





I knwo I haven't explained it very well, but I am from a laboratory background. Basically we use control variables to ensure the experiment can be replicated, and the dependant variables are things we alter in order to see what effect they have on the experiment.





For social studies it is less clear cut as you are gathering information and not actually changing anything.|||Control variables are the variables that are not changed throughout the trials in an experiment. They are kept constant to minimize the effects of the outcome and are used as a comparison. Dependent variables are the variables that change in response to an independent variable (a variable that is manipulated). In this study, the dependent variable is how much television a child watches. The independent variable is not stated in the question so the objective of the experiment is not clear, but an example could be age. The control variables are gender, race, and education because in order to perform a controlled experiment, all other variables must be kept the same so you can be sure that the independent variable is then one affecting the outcome.
