Experimental Methods

• Aim: General statement that describes the purpose of the study
• Hypothesis: A prediction of the results of an experiment that is tested.
• Directional Hypothesis: A hypothesis that predicts the direction of the relationship between two variables.
• Non-directional hypothesis: A hypothesis that does not specify the direction of the relationship between the independent and dependent variables.
• Independant Variable: The variable that is manipulated by the researcher to determine the effect of the other variable.
• Dependant Variable: The variable that is measured or changed by the independent variable.
• Operationalisation: Clearly defining variables so it can be measured accuratley
• Experimental Method: Involves the manipulation of the IV, in order to discover the effects of the DV
