Operationalising means phrasing things to make it clear how your variables are manipulated or measuredAn operationalised hypothesis tells the reader how the main concepts were put into effect.
8 marks A 8-mark apply question awards 4 marks for describing the experimental method AO1 and 4 marks for applying the Cognitive Approach to this AO2. It illustrates the power of the experimental method making use of clever experimental controls to isolate and remove confounding extraneous variables It shows the importance of experimental design since it uses both Independent Groups and Repeated Measures. 8 marks A 8-mark apply question awards 4 marks for describing the use of research design AO1 and 4 marks for applying the Cognitive Approach to this AO2. However they are often used as part of an experimental design as a way of gathering information about the independent variable IV or of measuring the dependent variable DV.
