Answer:

controlled experiment

Step-by-step explanation:

Controlled experiment is a type of experiment in which except for only one variable, everything is kept constant.

The common type of the controlled experiment compares the control group against the experimental group. All the variables are identical between two groups except factor which is being tested.

Big advantage of the controlled experiment is that one can eliminate much of uncertainty about the results.
