Detailed explanation-1: -The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores since that is what is being measured.
Detailed explanation-2: -In an experiment, the independent variable is the characteristic that is manipulated by the researcher to gauge the effect of the changes on the dependent variable. Note that, it is always the resulting change on the dependent variable that is measured by altering the independent variable.
Detailed explanation-3: -A dependent variable is the variable being tested in a scientific experiment. The dependent variable is ‘dependent’ on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded.
