what role do the independent and dependent variables play in a controlled experiment?
186689
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.

An independent variable is the variable that is changed in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable.

Independent variables are predetermined factors that one controls and/or manipulates in a designed experiment or an observational study. They are design variables that are chosen to incite a response of a dependent variable.

The dependent variable is the part of the experiment that reacts to the independent variable. The control is the base experiment for comparison with other trials of the experiment. Science experiments also include something called constants. A constant is the part that doesn't change during the experiment.

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.

The independent variable is "independent" because its variation does not depend on the variation of another variable in the experiment/research project. The independent variable is controlled or changed only by the researcher. This factor is often the research question/hypothesis behind the outcome of the experiment.

In research design, independent variables are those that a researcher can manipulate, whereas dependent variables are the responses to the effects of independent variables.

The values of the independent variable and the impact on the dependent variable are recorded. An experiment may include multiple experimental groups at one time. A control group is a group separated from the rest of the experiment such that the independent variable being tested cannot influence the results.

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.

The dependent variable is the variable that is being measured or tested in an experiment. ... In a psychology experiment, researchers are looking at how changes in the independent variable cause changes in the dependent 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.
1316815
The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected.

The two main variables in an experiment are the independent and dependent variable. 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.

An independent variable is a variable that represents a quantity that is being manipulated in an experiment. A dependent variable represents a quantity whose value depends on those manipulations.

They are alternatively called these names because of their role in research experiments. Independent variables are the variables that determine how dependent variables vary, i.e. they predict dependent variables. Dependent variables, on the other hand, are the variables being predicted by the independent variables.

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.
