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.
