control sample
Untreated comparison group
A control sample is a baseline specimen in an experiment that receives no treatment or manipulation, allowing researchers to measure what happens naturally without intervention.
By comparing experimental samples against the control, scientists can determine whether observed effects result from the variable being tested or from other factors.
The control sample showed no bacterial growth, confirming the antibiotic's effectiveness.
