In a controlled experment how are the control and experimental groups the same How are they different?

In a controlled experiment, the control and experimental groups are similar in that they are both exposed to the same environment and conditions, ensuring that any differences observed are due to the variable being tested. The primary difference lies in the treatment they receive: the experimental group is subjected to the specific variable or treatment being studied, while the control group does not receive this treatment and is used as a baseline for comparison. This design helps isolate the effects of the treatment and ensures the validity of the experiment's results.
