Self-experimentation has value in rapidly obtaining the first results. In some cases, such as with Forssmann's experiments done in defiance of official permission, results may be obtained that would never otherwise have come to light. However, self-experiment lacks the statistical validity of a larger experiment.
Also referred to as Personal science or N-of-1 research, [1] self-experimentation is an example of citizen science, [2] since it can also be led by patients or people interested in their own health and well-being, as both research subjects and self-experimenters.
{{Liberty | state = expanded}} will show the template expanded, i.e. fully visible. {{Liberty | state = autocollapse}} will show the template autocollapsed, i.e. if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar, but if not, it is fully visible.
The reversal design is the most powerful of the single-subject research designs showing a strong reversal from baseline ("A") to treatment ("B") and back again. If the variable returns to baseline measure without a treatment then resumes its effects when reapplied, the researcher can have greater confidence in the efficacy of that treatment.
In design of experiments, single-subject curriculum or single-case research design is a research design most often used in applied fields of psychology, education, and human behaviour in which the subject serves as his/her own control, rather than using another individual/group. Researchers use single-subject design because these designs are ...
For example, agricultural research frequently uses randomized experiments (e.g., to test the comparative effectiveness of different fertilizers), while experimental economics often involves experimental tests of theorized human behaviors without relying on random assignment of individuals to treatment and control conditions.
A strong research design yields valid answers to research questions while weak designs yield unreliable, imprecise or irrelevant answers. [ 1 ] Incorporated in the design of a research study will depend on the standpoint of the researcher over their beliefs in the nature of knowledge (see epistemology ) and reality (see ontology ), often shaped ...
To change this template's initial visibility, the |state= parameter may be used: {{Experimental design | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Experimental design | state = expanded}} will show the template expanded, i.e. fully visible.
