Preferred Label : Experimental Unit;
NCIt related terms : ExperimentalUnit;
NCIt definition : A physical entity which is the primary unit of interest in a specific research objective.
In an interventional study, the experimental unit is assigned to an intervention.
The experimental unit is also the unit of primary statistical analysis. Commonly the
individual study subject (animal, person or product) is the experimental unit. Different
experimental units must be capable of receiving different experimental interventions.;
Alternative definition : BRIDG 3.0.3: A physical entity which is the primary unit of interest in a specific
research objective. In an interventional study, the experimental unit is assigned
to an intervention. The experimental unit is also the unit of primary statistical
analysis. Commonly the individual study subject (animal, person or product) is the
experimental unit. Different experimental units must be capable of receiving different
experimental interventions. EXAMPLE(S): EXAMPLE(S):If all pigs in a pen receive the
same intervention in their feed, and the primary observations and analyses of interest
are associated with the entire pen (e.g. total feed consumed, total weight of all
pigs combined), then the pen of pigs rather than the individual animal is the experimental
unit. [CDISC/HL7 Study Participation RMIM, PORT_RM100001UV]A human StudySubject may
have 10 patches of skin each considered an ExperimentalUnit, or a Product StudySubject
may have 10 bearings in it, each considered an ExperimentalUnit. Alternatively, each
StudySubject may be an ExperimentalUnit. NOTE(S): Depending on the research objectives,
a single study may have multiple levels of experimental units, such as whole people
and patches of skin.; BRIDG 5.3: A physical entity which is the primary unit of interest in a specific research
objective. EXAMPLE(S): If all pigs in a pen receive the same intervention in their
feed, and the primary observations and analyses of interest are associated with the
entire pen (e.g. total feed consumed, total weight of all pigs combined), then the
pen of pigs rather than the individual animal is the experimental unit. [example from
the CDISC/HL7 Study Participation message] A human may have 10 patches of skin each
considered an experimental unit. A product may have 10 bearings in it, each considered
an experimental unit. Alternatively, the whole human or product may be an experimental
unit. OTHER NAME(S): NOTE(S): Depending on the research objectives, a single study
may have multiple levels of experimental units, such as whole people and patches of
skin. In an interventional study, the experimental unit is assigned to an intervention.
The experimental unit is also the unit of primary statistical analysis. Commonly the
individual study subject (animal, person or product) is the experimental unit. Different
experimental units must be capable of receiving different experimental interventions.; CDISC-GLOSS: A physical entity which is the primary interest in a specific research
objective. NOTE: Depending on the research objectives, a single study may have multiple
levels of experimental units. Commonly the individual study subject (animal, person
or product) is the experimental unit. (BRIDG v5.3); CDISC: A physical entity which is the primary unit of interest in an experimental
