Answer

Brief Explanations:

In a controlled experiment, the independent variable is the one manipulated by the experimenter to observe its effect on the dependent variable. All other factors are kept constant to isolate the relationship between the two variables.

Answer:

The independent variable is changed to see its effect on the dependent variable while all other conditions are unchanged.
