Answer 1

The test (independent) variable in this experiment is the color of the water. An independent variable is a variable that can be manipulated or vary in an experimental study to explore its effects. The independent variable is the cause.

Independent variables are the variable which the experimenter changes to test their dependent variable. A switch in the independent variable directly causes a change in the dependent variable. The result on the dependent variable is studied and noted.

There are two main types of independent variables; Experimental independent variables and Subject variables.

The independent variable is the component that can be changed in an experiment.
