so you can try to see exactly which factors are affecting the dependent variable (the thing you're measuring) "it gives you something to compare your results to" is the basic Y9-GCSE answer =]
A standard is necessary for calibration and validation of the results. Quality control and quality assurance obligatory involve standards.
Inorder to get more accurate results
Constants are factors in an experiment that stay the same. This should not be confused with controls -- which is a standard used for comparison

* independent variable:in an experiment there is only one variable and its set by the person carrying out the experiment . * dependent variable: measured in all set ups during the investigation. * controlled variables: are quantities that the scientist wants to keep constant. so , the part of the experiment that does not depend on the variable is the controlled variable.

experiment
A set of controlled observations that test a proposed explanation are known as an experiment. The proposed explanation is known as the hypothesis of the experiment.
controlled experiment
When referring to a science experiment, the standard for comparison would be a controlled experiment because it uses only one variable and is reliable.
experiment
the answer is a experiment that is controlled

It is called a controlled experiment.
