What is the difference between an 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 independent variable in science?
Its the variable that is different between the control and test parts of the experiment.
Define manipulated responding and controlled variables?
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.
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 is the difference of independent variable and a dependent variable?
An independent variable is when you do not control what happens In an experiment,however; a dependent variable is when you actually control the experiment,
How does randomization in an experiment combat response bias?
Response bias cannot be eliminated, but it should cancel out between the treatment and control groups.
The goal of using replication control randomization and blindness in experimental design is to compeletey eliminate bias from an experiment?
False
What is group that receives no treatment in an experiment?
the control.
What is the different between the control and experimental group?
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable. The difference (or similarities) between the two groups is how your results are measured.A control group is the group used for comparison in an experiment. One group receives the treatment that is being tested by the experiment; another group (the control group) has the exact same controlled environment, but does not receive this treatment. The effectiveness of the treatment can then be established by comparison with the control group.

Are control groups and experimental groups the same thing?
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable.

The effectiveness of the treatment can then be established by comparison with the control group.
In an experiment a group that receives no treatment is called what?
A group that receives no treatment is called the control group. The control group is there to compare the results between a group that has been exposed to diffent conditions, and one that has not.
The group that does not receive the experimental treatment in an experiment is the?
control group
In a controlled experiment what group recevies some type of treatment?
An experimental group is the group in an experiment that receives some type of treatment. The control group in an experiment receives no treatment. And, in conclusion, sometimes it might not work so be careful!!! :)
What does no treatment control mean as a science definition?
When there is treatment control in an experiment, it means that the specimen in that experiment has not been altered in any way. So no treatment control means the exact opposite. For example, a plant is let to grow naturally while another may have the tips of its shoot cut off. The shoot with its tips cut off has no treatment control.
What is the difference between control and controlled variable?
control is when nothing is done to the experiment and controlled variable is that you have control over the experiment.
In an experiment the group that received no treatment is called a?
In such cases the group is called the control group.
