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 is The key difference between an experimental and a quasi-experimental study is that the quasi-experimental study?
The key difference between an experimental and a quasi-experimental study is that a quasi-experimental study does not involve random assignment of participants to treatment or control groups. Instead, it often relies on existing groups or conditions, making it less controlled than a true experimental study. This lack of randomization can lead to potential confounding variables affecting the results, which makes it more challenging to establish causal relationships.
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.
What is primary advantage of the experimental method?
The primary advantage of the experimental method is its ability to establish cause-and-effect relationships between variables. By controlling conditions and manipulating an independent variable, researchers can isolate effects and draw conclusions about how changes impact outcomes. This level of control minimizes confounding factors, enhancing the reliability and validity of the results. Additionally, the experimental method allows for replication, which helps to confirm findings across different studies.
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.
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
Ask us anythingIn a controlled experiment what term is used to describe the many factors that might be different between the experimental and control groups?
In a controlled experiment, the term used to describe the many factors that might differ between the experimental and control groups is called "confounding variables." These variables can potentially influence the outcome of the experiment, making it difficult to determine whether the observed effects are due to the experimental treatment or other factors. Researchers aim to minimize these confounding variables to ensure the validity of their results.
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.
