Why is a variable used in an experiment?
Because it's an experiment not a replication...
A part of an experiment to which you can compare the results of other tests?
Control
What is the control group and what is it used for?
The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.
What is the control of a experiment?
The control of an experiment is the part of an experiment that does not change, and is strictly used as a comparison to the variable that is being tested.
Within the framework of an experiment how do you describe the independent variable dependent variable and the controlled variables?
In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome. The controlled variable is intended to be kept the same throughout the experiment so that changes in it do not affect the results.
What is a variable that doesn't change in an experiment called?
A variable that doesn't change in an experiment is called a constant. Constants are used to ensure that only one variable is being tested for its effect on the outcome of the experiment.
What is a n independent variable?
an independent variable is a figure usually shown as a letter that is used in the scientific theory. An independent variable is used in a hypothesized experiment in which this variable is unchanged and is used to effect the dependent variable somewhere in the experiment.

Control
What is the variable that stays the same in a experiment?
The variable that stays the same in an experiment is called the control variable. It is used as a baseline for comparison to see the effects of the manipulated variable.
What is a outcome variable in an experiment?
An outcome variable in an experiment is the variable that is being measured or studied to determine the effect of the independent variable. It is the variable that is expected to change as a result of manipulating the independent variable. The outcome variable is used to determine the success or failure of the experiment and to draw conclusions based on the results.
What is the difference between a controlled experiment and a variable?
In a control, the scientists know what to expect what will happen in an experiment... it is used for comparison.A variable is pretty simple. All it is, is the thing in the experiment that changes. There is usually only one of them in an experiment, and there are two kinds... Im sure you are familiar with them.-An independent variable is when the scientist controls what they are looking for-A dependent variable scientists dont control directly, but they measure for results
What variable does not change in an experiment?
The variable that does not change in an experiment is called the control variable. It is used as a benchmark for comparison to observe the effects of the other variables being tested.
Variable that does not change in an experiment?
A constant is a variable that does not change in an experiment. It is used as a point of reference or comparison to measure the effects of other variables.
What is the control group and what is it used for?
The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.
What is an example sentence with the word variable?
A fire siren has a variable tone.A fixed variable in a scientific study of humans might be gender or age.Variable weather conditions make it impossible to predict a tornado.
In an experiment what is the variable that stays the same during the entire experiment?
The variable that stays the same during the entire experiment is called the control variable. It is used as a baseline comparison to ensure that any changes observed in the experiment are due to the manipulated independent variable and not outside factors.
