Document Summary
Non experimental design: a design in which there is no control or manipulation of the variables. This design does not seek to establish cause and effect and instead focuses on describing or summarizing what takes place. Experimental design: a design in which the experimenter controls and manipulates the independent variable and makes comparisons between the different levels, allowing the establishment of cause-and-effect relationships between the independent and dependent variables. Independent variable (iv): the variable that influences the dependent variable. In experiments the researcher manipulates or controls this variable. Dependent variable (dv): the variable measured in association with changes in the independent variable; the outcome or effect. Factorial design: an experimental design that has more than one independent variable. Experimental realism: the degree to which a study participant becomes engrossed in the manipulation and truly influenced by it. Mundane realism: the degree to which a study parallels everyday situations in the real world.
