its called a fair test.

It's called a controlled experiment.
A variable in science is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by a scientist in the experiment. The depended variable is what you measure in the experiment and what is affected during the experiment. A controlled variable is one which the researcher holds constant (controls) during an experiment.
A variable of an experiment is anything that is changed either deliberately, or as a result of changing something else. An independent variable is one that is changed to obtain a different result. A dependent variable is the thing that changes as a result of changing the independent variable. There is also the controlled variable, or just control, which does not change throughout the experiment. A test or a trial
It is called a controlled experiment.
The independent variable is the one that is purposely changed to test a hypothesis.There are 3 kinds of variables in a scientific experiment: independent, dependent, and controlled.
The controlled variable is the type of soybean, and the changed variable is the type of water that the soybean is absorbing.
The controlled variables.
Controlled experiment. The thing you change is called the independent variable and the constants are the dependent variables. By only changing the independent variable, any results can be attributed to this.
The controlled variable is the variable that is kept constant , meaning not changed, throughout the entire experiment.
The three variable in an experiment are independent, dependent, and controlled. The independent is the variable you control, the dependent is the variable that will change according to the independent. The control is kept constant so they do not affect the dependent.
