negative control
Expected null result
In scientific experiments, a negative control is a test group that receives no treatment or a known inactive substance, establishing a baseline for comparison.
If the negative control shows no effect, researchers can be confident that any effect in the experimental group comes from the treatment itself rather than other factors: The saline injection served as a negative control.
