Variables that are always different between the experimental and the control groups are?
Independent variables.
If the treatment has no effect , the dependent variables for both the control and experimental group may be the same.
cw: In some studies, there is no specific control group. For instance, in a drug study where subjects are given a random amount of the drug (from 0 up to some presumed safe level) then you cannot easily tell what the "experimental" group is -- you can't compare everyone else to the two subjects who got a placebo (0 mg/kg). You can tell whether the treatment is having a linear effect, etc.

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.
What The one factor that differs between a control group and experimental group in a controlled experiment is the?
When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.
In biology what does control mean?
In biology, a control is a standard used for comparison in an experiment to ensure that any changes observed are due to the factor being tested and not other variables. Controls help to minimize the impact of confounding variables and confirm the validity of experimental results by providing a baseline for comparison.
What is the difference between control samples and test experimental samples?
It calculates the difference between each set of pairs, and analyzes that list of differences. The P value answersthis question: If the median difference in the ... If your samples are small and there are no tied ranks, Prism calculates an ... The whole point of using a paired test is to control for experimental.
What is an experimental control?
A group of experimental subjects that is not exposed to a chemical or treatment being investigated so that it can be compared with experimental groups that are exposed to the chemical or treatment. cw: An experimental control may be the control group. In general, the experimental control is something that allows you to say that the treatment effects on the experimental group are due to the treatments, rather than anything else.
In a controlled experiment what term is used to describe the many factors that might be different between the experimental and control groups?
variables
How do a control sample and an experimental sample differ from each other?
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
What do you call the variable that must remain the same between two groups?
The variables that must remain the same between the control group and experimental group is are called controlled variables, and include everything except the experimental variable.
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.
What is used as a way to compare values for a dependent variables in many experiments?
experimental control
What type of variables is experimental control?
Independent variable
What is the different between a control group and an experimental group in an experiment?
The control group does not change, while the experimental group is the variable you are changing.
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.
The purpose of blocking in experimental design is?
the control for multiple variables in a experiment
Why is experimental design is the strongest design for testing cause and effect relationships?
Experimental design is considered the strongest for testing cause and effect relationships because it allows researchers to manipulate independent variables to observe their effect on dependent variables while controlling for extraneous factors. This control enables researchers to establish a direct causal relationship between the variables being studied. By randomly assigning participants to different experimental conditions, experimental design helps to minimize bias and increase the internal validity of the study findings.
Are the control and experimental groups are designed to be identical?
In an ideal experimental design, the control and experimental groups are designed to be as similar as possible, with the only difference being the specific treatment or intervention that the experimental group receives. This helps to isolate the effect of the treatment and minimize the impact of other variables on the outcome of the study.
What is used as way to compare values for dependant variables in many experiments?
experimental control
