2023-2025 Year 12 A-Level Psychology INTRO Research Methods: IV DV
This flashcard set covers key concepts in A-Level Psychology Research Methods, focusing on Independent and Dependent Variables. It helps students understand how researchers manipulate the IV and measure its effects on the DV to identify cause-and-effect relationships.
What is an Independent variable?
The variable that changes OR is manipulated by the researcher to see if it has an effect on the DV.
