Do all experiments need a control group?

Yes, because if there is no control group, the results of the experiment are meaningless. If i had two plants, one I used miracle-grow on and the other I never watered, I wouldn't know if either of my variations (not watering and using miracle-grow) were meaningful without having another plant which lived a normal life (with adequate water) to compare it to.

Why would you need a control when experimenting on people?

A control group is essential in experiments involving people to measure the effect of the treatment by comparing it to a group that does not receive the treatment. This helps ensure that any changes observed are actually due to the treatment being tested and not other factors. Controls help to minimize bias and increase the reliability of the results.
