A controlled variable is one which you try to keep constant. The independent variable is the on that you change. The dependent variable is the one you measure.
For instance, how much will a drink cool down in one minute when you add a certain number of ice cubes to it?
The independent variable is the number of ice cubes. The dependent variable is the temperature drop.
There are many possible controlled variables: the starting temp of the drink, the size of the ice cubes, the type of glass, the air temperature, and so on.

the independent variable is changed, and the experimental value measure. So you control the independent variable and change it to measure the results
The controlled variable is the one that you chose to change while the dependant is the variable that changes because it is effected by the controlled variable
independent variable is the one you control. the dependent variable depends on the indepdendent variable (the results). on the graph independent in on the bottom and dependent is on the side
i think depednant variable is what youre gonna keep the same and independent variable is what youre changing , hope that helped!.....
An independent variable can be any of a given set of values while a dependent variable is represented as a function of another variable.
