EVERYDAY SCIENCE

Detailed explanation-1: -The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

Detailed explanation-2: -The independent variable is the variable the experimenter manipulates or changes and is assumed to directly affect the dependent variable. For example, allocating participants to drug or placebo conditions (independent variable) to measure any changes in the intensity of their anxiety (dependent variable).

Detailed explanation-3: -Dependent Variable The variable that depends on other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables. It is the presumed effect.

Detailed explanation-4: -Independent Variable (Treatment Variable) Definition and Uses.

Detailed explanation-5: -In the experimental method of research, the independent variable is manipulated to observe and measure its effect on the dependent variable. Experimental Method: Experimental research is research conducted with a scientific approach using two sets of variables.
