What are the factors that can change in an experiment called?

Answer 1

Environmental factors if you cannot control them.

Variable factors if you can control them.

See link below for easy explanation:

In an experiment the scientist is able to change the independent variable. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens. - See more at: http://www.chacha.com/question/what-part-of-an-experiment-is-the-factor-that-you-change#sthash.iyH25Jac.dpuf

Answer 2

In experimental design, this factor is called the Independent Variable. In an improperly conducted experiment, these factors are called variables. It would be improperly conducted because in an experiment, there is only supposed to be one independent variable at a time.

If you mean factors that are meant to stay the same, it varies on the experiment but usually environmental conditions and time experiment was conducted are controlled variables

Answer 3

changable factors

Answer 4

variables
