What is the scientific definition for a control?
A control is a known setup for a given experiment that is known to have no effect on the outcome, that it will remain constant throughout all tests. It is part of a test group that does not change, so as to compare results in the end.
An experiment setup in which the independent variable is not present is called the?
When conducting experiments in science, it is important to have a baseline for knowing what happens if an independent variable is not present. In science, this is called the control experiment.
What is the variable setup in an experiment called?
Independent variable
What is a constant setup experimental setup control setup and an experimental variable?
Control SetupThe constant control set up is where you have every thing "normal" to use to compare your experimental set up with the variable to. This has no variables and is always constant. For example if you wanted to see if plants would grow faster watered with sugar water or plain tap water, your constant control set up would be the plant watered with plain water. Since this is the "normal" condition with no changes it is the control setup.Additionally there are two kinds of controls, positive and negative. Positive controls will have an indication or contain the specific substance that the test or instrument is used for. On the other hand, negative controls don't contain that specific substance or instrument. For example if you were testing the effects of aspirin on inflammation and you gave a group, 20 mgs of a placebo, that would be a negative control. Opposite to that would be a positive control, if you were testing the same thing and instead gave the group 20 mgs of the aspirin.Experimental SetupIn short the part of the experiment that contains the variable is called the experimental setup. This is identical to the control setup except in one way. One change is made to the set up, this change is called the variable. In the example of the plants watered with tap or sugar water, the experimental set up would be the plant watered in the sugar water. Since this is the setup an which you are testing this, it is called the experimental (think of the experimental setup as a test) setup.Experimental variableThe experimental variable is basically what you are changing between the control and experimental setups.In the example, your experimental variable would be what the plant is watered with. So in this case, it would be the sugar water.
What is a experimental group?
In a scientific experiment it is common to split your sample into (at least) two groups. Say you were to study the effect of a new drug on a specific condition, you would have a sample (a group of people with the condition in question e.g. breast cancer), and you would treat all members of the sample the same, with the exception that one group is give the actual drug, and the other group is given a "fake" pill. This fake pill is also called a placebo. The group that is given the real drug is called the experimental group, and the group that is give the placebo is called the control group. This setup attempts to ensure that any effect that is observed is caused by the drug (the experimental condition).
2 kinds of setup in an experiment?
control and experimental setup
Why is control setup necessary in an experiment?
Without controlled setup in an experiment. How can the researcher know his data is comparable for study?
What is a setup that provides a standard for comparison in an experiment?
Answer The "Control"
What is the setup that provides a standard for comparison in an experiment?
Answer The "Control"
What is the purpose of the control setup?
To have something to compare the rest of the experiment to
What do control setup and experimental setup have in common?
Everything except what you're measuring. EXAMPLE: In a biological experiment using specially treated cells the experiment is run with the cells; this is the experiment. Then the experiment is run again with the same cells WITHOUT the special treatment; this is the control.
What is the purpose of a control setup in an experiment?
A control setup is something where you know how it will behave. It gives you a reference to measure affect of all other variables.
What is the scientific definition for a control?
A control is a known setup for a given experiment that is known to have no effect on the outcome, that it will remain constant throughout all tests. It is part of a test group that does not change, so as to compare results in the end.
What is the control setup of an experiment?
only 1 parameter, or, variable, is manipulated at a time
What is experimental setup?
were you setup your own experiment
An experiment setup in which the independent variable is not present is called the?
When conducting experiments in science, it is important to have a baseline for knowing what happens if an independent variable is not present. In science, this is called the control experiment.
What is used to separate the setup for an experiment from the surroundings?
Doggies
