Experimental techniques — Experimental research designs are used for the controlled testing of causal processes. The general procedure is one or more independent variables are manipulated to determine their effect on a dependent variable. These designs can be used where:… … Wikipedia
Variable-sweep wing — A Variable sweep wing is an aeroplane wing that may be swept back and then returned to its original position during flight. It allows the aircraft s planform to be modified in flight, and is therefore an example of variable geometry.Typically, a… … Wikipedia
Effect size — In statistics, an effect size is a measure of the strength of the relationship between two variables in a statistical population, or a sample based estimate of that quantity. An effect size calculated from data is a descriptive statistic that… … Wikipedia
experimental condition — noun the procedure that is varied in order to estimate a variable s effect by comparison with a control condition • Syn: ↑condition • Hypernyms: ↑procedure, ↑process • Part Holonyms: ↑experiment, ↑experimentation … Useful english dictionary
Instrumental variable — In statistics, econometrics, and related disciplines, the method of instrumental variables (IV) is used to estimate causal relationships when controlled experiments are not feasible. Statistically, IV methods allow consistent estimation when the… … Wikipedia

Hawthorne effect — The Hawthorne effect is a form of reactivity whereby subjects improve or modify an aspect of their behavior being experimentally measured simply in response to the fact that they know they are being studied,[1][2] not in response to any… … Wikipedia
Local hidden variable theory — In quantum mechanics, a local hidden variable theory is one in which distant events are assumed to have no instantaneous (or at least faster than light) effect on local ones. According to the quantum entanglement theory of quantum mechanics, on… … Wikipedia
Bayesian experimental design — provides a general probability theoretical framework from which other theories on experimental design can be derived. It is based on Bayesian inference to interpret the observations/data acquired during the experiment. This allows accounting for… … Wikipedia
Extraneous variable — Extraneous variables are variables other than the independent variable that may bear any effect on the behaviour of the subject being studied.ClassificationExtraneous variables are often classified into three main types: #Subject variables, which … Wikipedia
Quasi-experimental design — A quasi experiment is a scientific research method primarily used in the social sciences. “Quasi” means likeness or resembling, so therefore quasi experiments share characteristics of true experiments which seek interventions or treatments. The… … Wikipedia
