What do you call a sample that goes through all the steps of an experiment except the one being tested?
The control, or control group, goes through all the steps of an experiment, but does not contain the factor being tested, which is called the experimental variable or independent variable.
What is an controlled experiment?
A controlled experiment can be used to test almost anything. In a controlled experiment, the scientist (or experimenter) use a control group and an experimental group. The control group has nothing changed about it, and experiment group is changed based on the variable of the experiment. One of the most common uses of controlled experiments is the testing of new medications. In a medical study, a pharmaceutical company usually brings in a group of 100 people. Those people people are randomly assigned to two groups of 50. The experiment group is given the medication being tested, and the control group is given a placebo (a sugar pill). After several weeks, the experimenter can then see the side-effects of the medication, by comparing the differences between the experiment and control groups.
Conducted by performing two tests that are identical except for one fsctor called the?
manipulated variable
How do people get fingerprints?
Every person has a unique (except for identical twins) genetic code that defines what their fingerprints will be. We are born with them.
No two human individuals are alike except for identical twins The chief cause of the variation among individuals is?
Sexual recombination
The biology term of control?
A control group in an experiment is a group or individual that serves as a standard of comparison with another group or individual to which it is identical except for one factor.
Control and experimental groups are identical except for what?
Independent variable.
Control and experimental groups are identical except for the?
Independent variable
Experiments that involve two tests that are identical except for one factor?
A controlled experiment involves two tests that are identical except for one factor, which is the independent variable. The effect of the independent variable is the one being tested.
How many types of variable should be control in an experiment?
Ideally you control all variables except for the variable of interest.
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.
Part of the experiment that does not change?
the procedure doesn't change except for one controlled 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.

What is the difference between a control and a constant?
A control is a duplicate setup of the experiment you are performing with everything identical except for the variable that you are testing. Or, it is how the experiment would happen naturally, without you doing anything. For example, if you are testing the effects of a certain medication on humans, you give half of the subjects the medication and the other half a placebo, which is a sugar pill that has no effect. The latter group is the "control group". Their purpose is to remove the psychological effect of taking the medication from the results of the experiment, so that the only variable remaining is the actual effects of the medication. Constants are things that are kept the same for all trials, like making sure that every subject is taking a pill (and that they believe it is the medication in question, ever if it is only a placebo)
