In cognitive psychology, cognitive load is the effort being used in the working memory.According to work conducted in the field of instructional design and pedagogy, broadly, there are three types of cognitive load: intrinsic cognitive load is the effort associated with a specific topic; extraneous cognitive load refers to the way information or tasks are presented to a learner; and germane ...
Extraneous variables, if included in a regression analysis as independent variables, may aid a researcher with accurate response parameter estimation, prediction, and goodness of fit, but are not of substantive interest to the hypothesis under examination. For example, in a study examining the effect of post-secondary education on lifetime ...
A revision of a Wikipedia article shows a troll vandalizing an article on Wikipedia by replacing content with an insult.. In slang, a troll is a person who posts deliberately offensive or provocative messages online [1] (such as in social media, a newsgroup, a forum, a chat room, an online video game) or who performs similar behaviors in real life.
Extraneous solutions are not too difficult to deal with because they just require checking all solutions for validity. However, more insidious are missing solutions, which can occur when performing operations on expressions that are invalid for certain values of those expressions.
In this context the extraneous variables can be controlled for by using multiple regression. The regression uses as independent variables not only the one or ones whose effects on the dependent variable are being studied, but also any potential confounding variables, thus avoiding omitted variable bias .
Confounding is defined in terms of the data generating model. Let X be some independent variable, and Y some dependent variable.To estimate the effect of X on Y, the statistician must suppress the effects of extraneous variables that influence both X and Y.
Pleonasm (/ ˈ p l iː. ə ˌ n æ z əm /; from Ancient Greek πλεονασμός pleonasmós, from πλέον pléon ' to be in excess ') [1] [2] is redundancy in linguistic expression, such as in "black darkness," "burning fire," "the man he said," [3] or "vibrating with motion."
Geographic redundancy corrects the vulnerabilities of redundant devices deployed by geographically separating backup devices. Geographic redundancy reduces the likelihood of events such as power outages, floods, HVAC failures, lightning strikes, tornadoes, building fires, wildfires, and mass shootings disabling most of the system if not the entirety of it.
