In a controlled experiment what term is used to describe the many factors that might be different between the experiment and control groups?
Variables
The part in a controlled experiment that receives some kind of treatment or condition and is compared to the control group is called?
Controlled experiments contain two parts, the control group and the variable group. The variable group is the group that receives treatment and attention. These two groups are used to compare to each other at the end of the experiment.
A controlled experiment compares two situations that?
have no variables
What are two types of scientific investigations that scientist use when a controlled experiment is not practical?
When a controlled experiment is not possible or practical, two types of scientific investigations are observation and modeling.
In a research study if one variable is changed to see how it affects behavior the study is most likely a?

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.
What is the correct definition for controlled experiment?
the answer is a experiment that is controlled
What is the difference between experimental group and controlled 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.
What is an experiment which only one variable is changed?
It is called a controlled experiment.
