what is the experimental group

The experimental group is the group in a study that receives the treatment or change being tested. Researchers compare it with a control group to see whether the treatment caused any difference.

Quick example

If a scientist is testing a new fertilizer:

• Experimental group: plants that get the new fertilizer.
• Control group: plants that do not.

Why it matters

This setup helps researchers isolate the effect of one variable while keeping everything else as similar as possible.

If you want, I can also explain the difference between the experimental group and the control group in one simple table.
