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.
