A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable (i.e. confounding variables). [1] This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
Those conditions are: 1) the electronic transferable record shall contain all information required for the corresponding paper-based transferable document or instrument; 2) a reliable method shall be used: a) to identify the electronic transferable record as such; b) to render the electronic transferable record subject to control throughout its ...
A clinical control group can be a placebo arm or it can involve an old method used to address a clinical outcome when testing a new idea. For example in a study released by the British Medical Journal, in 1995 studying the effects of strict blood pressure control versus more relaxed blood pressure control in diabetic patients, the clinical control group was the diabetic patients that did not ...
Transfer-appropriate processing (TAP) is a type of state-dependent memory specifically showing that memory performance is not only determined by the depth of processing (where associating meaning with information strengthens the memory; see levels-of-processing effect), but by the relationship between how information is initially encoded and how it is later retrieved.
The control laws may be represented by high order transfer functions required to simultaneously accomplish desired disturbance rejection performance with the robust closed-loop operation. High-gain feedback is the principle that allows simplified models of operational amplifiers and emitter-degenerated bipolar transistors to be used in a ...
Feyerabend began writing Against Method in 1968 [3] and it was originally released as a long paper in the Minnesota Studies in the Philosophy of Science series in 1970. At the behest of Lakatos, who originally planned to write For Method in contrast to Against Method but then died, [3] the paper was expanded into a book published in 1975.
Goodhart's law is an adage often stated as, "When a measure becomes a target, it ceases to be a good measure". [1] It is named after British economist Charles Goodhart, who is credited with expressing the core idea of the adage in a 1975 article on monetary policy in the United Kingdom: [2]
A randomized controlled trial (or randomized control trial; [2] RCT) is a form of scientific experiment used to control factors not under direct experimental control. Examples of RCTs are clinical trials that compare the effects of drugs, surgical techniques, medical devices , diagnostic procedures , diets or other medical treatments.
