Encyclopedia
In the design of experiments
, treatments are applied to experimental units in the treatment group(s), while no treatments would be applied to members of a control group.
When analyzing data, the treatments are specified either as numerical values or as levels of a factor. When several different treatments are being studied at the same time, a given subject or item in the experiment would be described by values or factors associated with each of the different treatments, as well as by any observed outcomes from the experiment.
