Controlled variables are things that may effect the outcome of an experiment, like temperature are pressure or the amount of some substance used.
Dependent variables are those which change due to the conditions mentioned above.
These might be speed of the reaction, or the quantity of some product.
Dependent Variable
In a controlled experiment, the Independent variable refers to the variable that is manipulated or altered. The dependent variable, meanwhile, is the result of the experiment.
The two types of variables in an experiment are independent variables, which are controlled by the experimenter and can be manipulated, and dependent variables, which are the outcome or response that is measured in the experiment and may change in response to the independent variable.
the things you change
In a controlled experiment only 1 variable is being tested.
The number of dependent variables in an experiment varies, but there is often more than one. experiments also have controlled variables are quantities that a scientist wants to remain constant, and he must be observe them as carefully as the dependent variables.
Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.
The independent variable in an controlled experiment is what you are changing
Independent variables are controlled or manipulated by the researcher to determine their effect on the dependent variable. Dependent variables, on the other hand, are the outcome or response that is measured in an experiment. The independent variable causes a change in the dependent variable.
In an experiment, the three types of variables are independent, dependent, and controlled variables. The independent variable is the one that is manipulated by the researcher to observe its effect. The dependent variable is the outcome that is measured to assess the impact of changes in the independent variable. Controlled variables are those elements that are kept constant throughout the experiment to ensure that any observed effects are solely due to the manipulation of the independent variable.

The types of variables according to functional relationship are independent variables and dependent variables. Independent variables are inputs that are manipulated or controlled in an experiment, while dependent variables are the outputs that are affected by changes in the independent variables.
