The term that describes the environment or situation where the manipulated variables are actively present in an experiment is known as the treatment condition. In experimental research, the treatment condition refers specifically to the group or groups that receive the intervention or the changed variable that the researcher is testing. This allows the researcher to observe the effects of the manipulation on the dependent variables.

In contrast, the other terms refer to different aspects of experimental design. The dependent condition typically relates to the variables that are measured to assess the impact of the treatment. The independent condition, although it could sound relevant, does not accurately describe the environment but rather focuses on the factor that is deliberately manipulated by the researcher. The control condition is used as a baseline or comparison, consisting of a group that does not receive the treatment, allowing researchers to measure the effect of the treatment against a standard reference. Thus, treatment condition is the most precise term to capture the idea of actively manipulating variables in a given experimental setting.
