Final answer:
The experimental condition is where the independent variable is manipulated to observe its effect on the dependent variable, distinguishing it from the control condition.
Step-by-step explanation:
The condition in an experiment where the independent variable is manipulated is known as the experimental condition. In ideal experimental design, researchers compare results from the experimental group to those from the control group. The control group does not receive the experimental manipulation. Through random assignment, each group should be similar in all respects except for the presence of the independent variable in the experimental group, allowing researchers to observe the effects caused by the manipulation of that variable.
