it is called a constant - known as anything that can not be changed in an controlled experiment. 8th grade science
The independent variable, which is the factor being changed or manipulated by the researcher, should not be changed during the course of the experiment to maintain consistency and validity of the results.
The independent variable is the factor changed by the scientists.The dependent variable (think of it like this: it dependson the results of the experiment) is what is measured.
The variable that is being tested or changed by the person conducting the experiment is called the independent variable. It is the factor that is purposely manipulated in order to observe its effect on another variable, known as the dependent variable.
a controlled experiment
Well in the case that it does have a variable, even just one, it would still be a variable experiment because that one part of the experiment may still cause a different effect/result when changed!!!
