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).
