A single factor to be tested in an experiment is often referred to as an independent variable. This variable is manipulated to observe its effect on a dependent variable, which is measured in response. For example, in a plant growth experiment, the amount of sunlight (the single factor) can be tested to see how it affects plant height (the dependent variable). This approach helps isolate the impact of that specific factor while controlling for others.
a control
A factor that changes in an experiment is called a dependent variable. It is the variable that is being tested.
controlled variable
independent variable
The group in an experiment that is exposed to the factor being tested is called the experimental group. This group is compared to a control group, which is not exposed to the factor, to determine the effect of the variable being studied. By analyzing the differences between these groups, researchers can assess the impact of the tested factor on the outcome.
Control group
The factor being tested is the dependent variable.
The factor being tested is the dependent variable.
The factor that is being tested in an experiment is called a variable. The factor that is measured or observed is called the dependent variable.
The factor not being tested in an experiment is called a control variable. Control variables are kept constant throughout the experiment to ensure that any changes in the outcome can be attributed to the factor being tested.

The independent variable.
The dependent variable varies due to effects of the factor being tested in a controlled experiment.
