Which element of an experimental study is described as the procedures applied to each subject?

Responses are the outcomes or effects observed in subjects as a result of the treatments applied. While they are essential for evaluating the impact of the treatments, they do not describe the procedures themselves. Instead, responses are the data collected following the application of treatments.

Inputs refer to the resources or factors that are utilized in the experimental process, such as materials, time, or participant data. They do not specifically denote the procedures applied to subjects. Inputs are generally broader and can encompass various components of the study design, but they do not identify the actions taken during the experiment.

Experimental units are the subjects or entities to which treatments are applied in an experiment. While they represent the recipients of the treatments, they do not describe the procedures themselves. Experimental units focus on who or what is being studied rather than the methods used in the study.
