What is the difference between the independent variable and the experimental variable?
the independent variable is changed, and the experimental value measure. So you control the independent variable and change it to measure the results
What do you call an experimental setup in which the experimental variable is missing?
control setup
When a variable is kept unchanged in an experiment it is said to be?
It is called the control variable. It is used to compare to your experimental results.
What principles of experimental design ensures that the explanatory variable and not some variable over which the experimenter has no control is causing observed changes in the res?
Control
What characteristics must a problem possess in order for it to be studied scientifically?
It must have a control group, experimental group, and a experimental variable
What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between the independent variable and the experimental variable?

What is the difference between the control group and the experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is difference between the control group and the experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is the difference between an experimentation variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What are the difference between control set up and variable experimental set up?
The control variable is the thing you keep the same and is everything that is not the independent variable. The Control Setup is there for the sake of comparison.
What conditions must be met if you want to have a scientifically valid sample for a study?
You must have a control group, an experimental group, an experimental variable (also called the independent variable), and a response to be measured (also called the dependent variable). The experimental variable is applied only to the experimental group, so that any difference between the control group and experimental group is due only to the experimental variable. Both the control group and experimental group must have the same conditions, except for the experimental variable.
What is the difference between a conrtol group and an experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is the difference between control and experimental variables?
Control variables are kept constant throughout an experiment to ensure that any changes in the dependent variable are due to the manipulation of the independent variable. Experimental variables, on the other hand, are the factors that are deliberately changed by the researcher to observe their effect on the dependent variable.
Why is a control group important to have in a experiment?
A control group is the standard of comparison between what happens with the experimental variable and without the experimental variable.
What is the difference between a control variable and a control treatment?
A control variable is a factor that is held constant in an experiment to prevent it from influencing the outcome. A control treatment, on the other hand, is a specific group or condition in an experiment that receives no experimental manipulation and is used as a baseline for comparison with the treatment groups.
What is a factor in a experiment that you measure to gather results?
It is a variable. The independent (manipulated) variable is the factor that is different between the control and experimental groups. The dependent variable is the difference resulting from the independent variable. The controlled variables are the factors that are not changed in the experiment between the control and experimental groups.
