What do you call the subjects in an experimental research design that is given an intervention?
Single-subject experimental designs – also referred to as within-subject or single case experimental designs – are among the most prevalent designs used in CSD treatment research. These designs provide a framework for a quantitative, scientifically rigorous approach where each participant provides his or her own experimental control. Show

Single-subject studies should not be confused with case studies or other non-experimental designs.

[Article] [PubMed] When designing experimental research what is an intervention?Intervention research examines the effects of an intervention on an outcome of interest. The primary purpose of intervention research is to engender a desirable outcome for individuals in need (e.g., reduce depressive symptoms or strengthen reading skills).
What group in experimental research design is subjected to intervention?In a true experiment, the effect of an intervention is tested by comparing two groups. One group is exposed to the intervention (the experimental group, also known as the treatment group) and the other is not exposed to the intervention (the control group).
Does experimental research have intervention?Experimental studies are ones where researchers introduce an intervention and study the effects. Experimental studies are usually randomized, meaning the subjects are grouped by chance.
Which variable is the treatment or intervention in a study?The INDEPENDENT VARIABLE is the "treatment" or "intervention" that is being tested. The DEPENDENT VARIABLE is the behavior we want to change (the target behavior).
