What is a Extraneous variable? Best Answer: Extraneous Variables are undesirable variables that influence the relationship between the variables that an experimenter is examining. Another way to think of this, is that these are variables the influence the outcome of an experiment, though they are not the variables that are actually of interest.f you are looking for the answer to Xsquared + 1 = 26, then X can be either a +5 or a -5 so it is a variable. An extraneous variable would be a variable that does not really affect the answer or the experiment (as in 'an irrelevant variable'). Source(s): Me.

Longest Active Playoff Droughts in the MLB But even with all those factors in play, a few teams haven´t been so lucky. In the past 10 years, 26 of the 30 MLB franchises have been to the playoffs at least once (even the Cubs!), and now that the postseason features a third of the league, it is easy to predict that long playoff droughts will become more and more scarce over time.

Intervening variable For example, hunger is a hypothetical internal state which has been used to explain the relationships between independent variables such as length of time without food, or amount of food consumed, and dependent variables which are measures of eating.

Managing Vesicant Extravasations Extravasation is an unusual but potentially severe complication of vesicant chemotherapy administration. Some extravasation injuries prompt litigation and the oncologist's actions, or lack of action, are scrutinized in the courtroom.

Extrapolation In mathematics, extrapolation is the process of estimating, beyond the original observation range, the value of a variable on the basis of its relationship with another variable. It is similar to interpolation, which produces estimates between known observations, but extrapolation is subject to greater uncertainty and a higher risk of producing meaningless results. Extrapolation may also mean extension of a method, assuming similar methods will be applicable.

lurking variable Definition. A variable that correlates with the independent variable and the dependent variable in a statistical model. Lurking variables must be accounted for in statistical experiments, so that they do not generate false positives or otherwise generate non-meaningful results.

- Whatever the case may be, the researcher expects that the independent variable(s) will have some effect on (or relationship with) the dependent variables. intervening variables . . . refer to abstract processes that are not directly observable but that link the independent and dependent variables.

Australian Bureau of Statistics A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item. Age, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour and vehicle type are examples of variables.

Research Variables: Dependent, Independent, Control, Extraneous & Moderator An independent variable is a variable believed to affect the dependent variable. This is the variable that you, the researcher, will manipulate to see if it makes the dependent variable change. In our example of hungry people throwing a ball, our independent variable is how long it's been since they've eaten. To reiterate, the independent variable is the thing over which the researcher has control and is manipulating. In this experiment, the researcher is controlling the food intake of the participant.

independent variable For example, in a study of the effect of nursing intervention on postoperative vomiting, nursing intervention is the independent variable evaluated by its effect on the dependent variable, the incidence of postoperative vomiting. Also called experimental variable, predictor variable. Compare dependent variable.

Writers Workshop: Writer Resources Nonrestrictive Clauses. A nonrestrictive modifying clause (or nonessential clause) is an adjective clause that adds extra or nonessential information to a sentence. The meaning of the sentence would not change if the clause were to be omitted. Nonrestrictive modifying clauses are usually set off by commas. 1  Edgar Allan Poe, who wrote The Raven, is a great American poet. 2  Puerto Rico was a Spanish colony until 1898, when it was ceded to the United States.

What is a Extraneous variable? Extraneous Variables are undesirable variables that influence the relationship between the variables that an experimenter is examining. Another way to think of this, is that these are variables the influence the outcome of an experiment, though they are not the variables that are actually of interest. These variables are undesirable because they add error to an experiment. A major goal in research design is to decrease or control the influence of extraneous variables as much as possible.

- The independent variable is the variable that is manipulated during an experiment, and it gets its name because it is independent of other factors. It's the cause of the experiment that changes the dependent variable, which is the variable that is affected during an experiment.

What is an 'Endogenous Variable' What is an 'Endogenous Variable'. An endogenous variable is a classification of a variable generated by a statistical model that is explained by the relationships between functions within the model. For example, the equilibrium price of a good in a supply and demand model is endogenous because it is set by a producer in response to consumer demand. It is the opposite of an exogenous variable.

Extraterritoriality Extraterritoriality is the state of being exempted from the jurisdiction of local law, usually as the result of diplomatic negotiations. Historically, this primarily applied to individuals, as jurisdiction was usually claimed on peoples rather than on lands.

- Five Global Factors (16PF) Extraversion (Extraversion vs. Introversion) : examines general social participation level. Extraverts tend to be people oriented and seek out relationships with others. (A+, F+, H+, N-, Q2-) Introverts tend to be less outgoing, spending more time on their own than in the company of others. A strong correlation exists between Extraversion and measures of social desirability, Like the IM scale.
