The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. ... The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable.

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. The two variables may be related by cause and effect.

The independent variable is what is in the experimenters' control and the experimenter explicitly manipulates it. The dependent variable is the numerical measure of what the outcome of the manipulation should be: the data that the experimenter gathers.

The "independent variable" is the one that you think of as causal, the "dependent variable" is the one that you think of as being affected by the "independent variable." ... The way the terms "independent variable" and "dependent variable" are used these days causes much confusion and some mischief.

Dependent and independent variables. From Wikipedia, the free encyclopedia. In an experiment, the variables used can be classed as either dependent or independent variables. The dependent variable is the possible outcome of the experiment; the effect. It depends on what happens to other variables in the experiment.

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.

Independent variable: What the scientist changes or what changes on its own. Dependent variable: What is being studied/measured. The independent variable (sometimes known as the manipulated variable) is the variable whose change isn't affected by any other variable in the experiment.

Independent variable is the quantity that the Chemist causes to change. Dependent variable is the quantity that responds to the change the Chemist has caused.

Independent vs Dependent Variables An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

Summary: Independent vs Dependent Variable The independent variable is what you change, and the dependent variable is what changes as a result of that. You can also think of the independent variable as the cause and the dependent variable as the effect. ... Constant variables are also important to understand.

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.

An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable.

Remember, an independent variable is the part of the experiment the scientist changes or controls. The dependent variable is the part of the experiment that reacts to the independent variable. ... A constant is the part that doesn't change during the experiment.

Dependent Variable. 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.

Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. ... Any change in a controlled variable would invalidate the results.

An independent variable is a variable that represents a quantity that is being manipulated in an experiment. ... In the context of a function, the independent variables are the inputs to the function and the dependent variables are the outputs of the function.
