Because otherwise it will not be possible to know whether observed variations in the dependent variable are due to one independent variable or another.

What are the experimental variables?

Experimental variables are factors being tested or measured in a scientific experiment. They can be categorized as independent variables (manipulated by the experimenter), dependent variables (respond to the changes in the independent variable), and controlled variables (kept constant to prevent interference).

What are the types of variables according to functional relationship?

The types of variables according to functional relationship are independent variables and dependent variables. Independent variables are inputs that are manipulated or controlled in an experiment, while dependent variables are the outputs that are affected by changes in the independent variables.


What are the two types of variables in an experiment?

The two types of variables in an experiment are independent variables, which are controlled by the experimenter and can be manipulated, and dependent variables, which are the outcome or response that is measured in the experiment and may change in response to the independent variable.

In a controlled experiment, the Independent variable refers to the variable that is manipulated or altered. The dependent variable, meanwhile, is the result of the experiment.


What are three kinds of variables used in scientific investigation?

In scientific investigations, three key types of variables are independent variables, dependent variables, and controlled variables. The independent variable is the factor that is manipulated or changed by the researcher to observe its effect. The dependent variable is the outcome or response that is measured to assess the impact of the independent variable. Controlled variables are those that are kept constant throughout the experiment to ensure that any observed changes can be attributed solely to the independent variable.
