AP PSYCHOLOGY

Detailed explanation-1: -In the experimental method of research, the independent variable is manipulated to observe and measure its effect on the dependent variable.

Detailed explanation-2: -The independent variable, also known as the manipulated variable, is the factor manipulated by the researcher, and it produces one or more results, known as dependent variables.

Detailed explanation-3: -Experiments have two fundamental features. The first is that the researchers manipulate, or systematically vary, the level of the independent variable. The different levels of the independent variable are called conditions .

Detailed explanation-4: -Dependent variables are what researchers measure for in research studies. Dependent variables are not manipulated by researchers, as with independent variables. Dependent variables are the measurements or outcomes of interest that are being studied .

Detailed explanation-5: -Manipulation means that something is purposefully changed by the researcher in the environment. Control is used to prevent outside factors from influencing the study outcome. When something is manipulated and controlled and then the outcome happens, it makes us more confident that the manipulation “caused” the outcome.
