Control groups[edit]

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[1] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[2]"[3]

Proof of concept[edit]

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[4] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[5]

Proof of technology[edit]

"[T]he objective of a proof of technology is to determine the solution to some technical problem, such as how two systems might be integrated or that a certain throughput can be achieved with a given configuration."[6]

Def. "[a]n original object or form which is a basis for other objects, forms, or for its models and generalizations"[7] is called a prototype.

Def. "[a]n early sample or model built to test a concept or process"[7] is called a prototype.

Def. "[a]n instance of a category or a concept that combines its most representative attributes"[7] is called a prototype.

Def. "[t]o test something using the conditions that it was designed to operate under, especially out in the real world instead of in a laboratory or workshop"[8] is called "field-test", or a field test.

A "proof-of-technology prototype ... typically implements one critical scenario to exercise or stress the highest-priority requirements."[9]

"[A] proof-of-technology test demonstrates the system can be used"[10].

"The strongest proof of technology performance is based on consistency among multiple lines of evidence, all pointing to similar levels of risk reduction."[11]

Medicine[edit]

The diagram on the right shows the approximately proper locations to apply the adhesive electrodes for performing an electrocardiogram.

Cardiology[edit]

Theoretical electrocardiograms[edit]

Def. a "visual output that an electrocardiograph produces"[12] is called an electrocardiogram, or ECG, EKG.

EKG comes from the German term Elektrokardiogramm.
