Control variable definition: a person, group, event, etc., that is used as a constant and unchanging standard of comparison in scientific experimentation.. See examples of CONTROL VARIABLE used in a sentence.
Control variables refer to variables whose effects on an outcome variable are statistically adjusted in order to estimate independent effects of an explanatory variable. In its conventional usage, the term is limited to variables that are actually observed. This article discusses methods of controlling ...
As another control variable, a basic reading ability test was conducted, (Bräuerlein et al., Citation2012), since the experimental procedure relied in part on reading abilities. If we aim to identify effective learning activities to foster students’ understanding of the CVS, it seems ...

The switch statement is one of the control statements in R programming which is used to equate a variable against a set of values. Each value is called a case. The basic syntax for a switch statement is as follows: switch(expression, case1, case2, case3...) For example: x <- switch...

Ensuring reproducibility of results in high-throughput experiments is crucial for biomedical research. Here, we propose a set of computational methods, INTRIGUE, to evaluate and control reproducibility in high-throughput settings. Our approaches are built on a new definition of reproducibility that emphas...

a, An example trial. Each trial consisted of either one (load 1) and three (load 3) consecutively presented pictures, each presented for 2 s (separated by a variable blank screen of up to 200 ms as indicated by a small dot). After a variable maintenance period with an average dura...
