What type of scientific investigation involves identifying and controlling variables?
laboratory experiment
Which type of investigation has a control group?
Medical type investigations require a control group; there are other types as well which may require a control group. The idea is to limit that number of variables. When you are trying out a new drug, you also have a group that has the same medical condition (arthritis, whatever it may be) but you give them a placebo, generally a sugar pill, instead of the drug that you are testing. That way, in case there is some effect merely from the fact that people are taking a pill, you can find out the extent to which the actual chemical composition of the pill is contributing to the outcome.
Why is a control needed in an experiment?
The control group gives you something to compare the results to. For example, in a medical trial for a new medicine, one group will receive sugar pills. Without this control group, it means nothing if 50% of those treated with the real medicine get better. The control group may have the same results, better results, or worse results. This tells how effective the medicine is. The same is done with any type of experiment.
What is the meaning of control in science form?
a control is when someone is performing a science experiment, the control group is a test group that is kept neutral and is used as a standard of comparison, for example if you are doing an experiment on whether or not music affects concentration and you have 6 test groups, each listening to a different type of music, you would want one group to not listen to any music at all to compare to the other results.

What is the difference between a test group and control group?
A test group is the group in an experiment to which the change is being applied and the control group is the same type of group in an experiment to which nothing is done to compare the changes in the test group to.
Example of control group?
The control group is the one that is not manipulated in any way. Suppose we are testing the effect of studying on test scores. The group that did not study would be the control group. The group that did study would be the experimental group.
In a controlled experiment what group recevies some type of treatment?
