what does the independent and dependent variable mean?
47616
Variables are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable.

Dependent and Independent Variables An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.

The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. ... In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.

dependent variable. A factor or phenomenon that is changed by the effect of an associated factor or phenomenon called the independent variable. For example, consumption is a dependent variable because it is caused and influenced by another variable: income.

Dependent Variable: A dependent variable is what you measure in the experiment and what is affected during the experiment. ... It is called dependent because it "depends" on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable.

['The independent variable is the variable that is controlled and manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable.', 'The dependent variable is the variable that is measured by the experimenter.']

The independent and dependent variables are the two key variables in a science experiment. The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable.

An independent variable is a variable that is manipulated to determine the value of a dependent variable. ... a = b/c the independent variables, b and c, determine the value of a.

The independent variable is the variable that is not affected by other variables. Instead, it determines the value of other variables (particularly, the dependent variables). In experimental sciences in particular, it is the variable that is manipulated or controlled by the experimenter.

Dependent variables A dependent variable represents a quantity whose value depends on how the independent variable is manipulated. y is often the variable used to represent the dependent variable in an equation.

The dependent variable is the variable a researcher is interested in. The changes to the dependent variable are what the researcher is trying to measure with all their fancy techniques. ... An independent variable is a variable believed to affect the dependent variable.

A dependent variable. This is the variable we are trying to explain. We want to find out why the variable takes on the values that it does. An independent variable. This is the variable thought, directly or indirectly, to influence the value of the dependent variable.

The idea is that one variable is the effect of another variable or, to say it another way, that one variable precedes and/or causes another. The dependent variable is the variable to be explained (the 'effect”). The independent variable is the variable expected to account for (the “cause” of) the dependent variable.

The dependent variable is the variable that is being measured or tested in an experiment. ... When researchers make changes to the independent variable, they then measure any resulting changes to the dependent variable.

Independent variables are those which do not depend on other variables. Dependent variables are those which are changed by the independent variables. The change is caused by the independent variable. In our example salary is the independent variable and the amount you spend is the dependent variable.

The independent variables are the ones that are tested to see if they are the cause. The dependent variables are the properties that change when the independent variables change. ... To answer this question, you plot a graph with the independent variable along the x-axis and the dependent variable along the y-axis.
