A manipulated variable is essentially the same as an independent variable in the context of scientific research.
Here's an example. Suppose you were studying how quickly rats can navigate a maze to find food and you wanted to know the effect of hunger level. You could keep one group of rats hungry for four hours and another group hungry for eight hours then allow each rat in the two groups to find its way through the same maze to a quantity of food. You would measure the time it took each rat to find the food. The manipulated variable would be the time that a rat had been kept hungry.
A manipulated variable is not changed on purpose.
There is no answer to a manipulated variable because "a manipulated variable" is not a question!

controlled
It means the one factor that a scientist changes during an experiment; also called independent variable.
The manipulated variable is the variable that is changed in the experiment. The responding variable is the result of changing the manipulative variable, and the controlled variable is the variable that's stays the same throughout the entire experiment.
No. A manipulated variable is the same as an independent variable.
operational definition of a manipulated variable
The manipulated/independent variable is a variable that changes and it is what the responding/dependent variable change because of the manipulated variable.
In an experiment, the manipulated variable is also known as the independent variable. An example of the term "manipulated variable" in a sentence would be, "The scientist sincerely hoped that the manipulated variable would produce a reaction in the dependent variable."
The dependent variable may change in response to the manipulated variable.
