It is called a controlled experiment.
A controlled experiment.
controlled experiment
Independent variable. The dependent variable is the one that is affected by the independent variable, for example-y=2x+2This is the equation of a line. X is deliberately changed to find y hence - y is the dependent variable and x is the independent variable.
A dependent variable is a factor in an experiment that is influenced by another factor. An example might help to clarify. You are performing an experiment in which you are observing how sunlight affects plant height. Plant height is the dependent variable because it is dependent upon how much sunlight the plant receives. Sunlight is an example of an independent variable. It is not influenced by anything in this experiment, but may be changed to observe its effect on the dependent variable. It is possible to have more than one dependent variable in an experiment, but only one independent variable.
The variable that is being changed in the experiment is called the independent variable. The variable being tested is called the dependent variable. The constant is the one thing in the experiment that stays the same
The independent variable is the one variable that you change in your experiment

a controlled experiment
the investigator only changes one variable in an experiment because they need to see how that one variable reacts. if you wanted to see how the dependent variable changed but changed the independent variable you would not see how the one variable reacts.
