Detailed explanation-1: -In research, variables are any characteristics that can take on different values, such as height, age, temperature, or test scores. Researchers often manipulate or measure independent and dependent variables in studies to test cause-and-effect relationships.
Detailed explanation-2: -The two main variables within a study are the independent variable, which is the variable that is manipulated by the experimenter, and the dependent variable, which is the variable that indirectly changes due to the manipulation in the independent variable.
Detailed explanation-3: -An independent variable is the presumed causal variable in a relationship, and the dependent variableis the presumed effect variable (Kerlinger, 1986).
Detailed explanation-4: -Therefore, in experiments, a researcher manipulates an independent variable to determine if it causes a change in the dependent variable.
