What term refers to the standard in an experiment where tested factors are not applied?

The term that refers to the standard in an experiment where tested factors are not applied is the control. In scientific experiments, a control group serves as a baseline that allows researchers to compare the effects of the independent variable. It typically consists of the same conditions as the experimental group, except for the factor being tested. This is crucial in determining whether the variable being tested truly has an effect on the outcome.

For example, if researchers were testing a new fertilizer's effectiveness on plant growth, the control group would consist of plants that do not receive the fertilizer, while the experimental group would receive it. By comparing the growth of both groups, researchers can assess the fertilizer's impact accurately. Without a control, it would be challenging to draw meaningful conclusions about the variable's effect.
