Welcome!Today we’ll explore Unit 2: Planning and Conducting Psychological Research. This unit focuses on understanding research methods, ethical considerations, and data analysis. Let’s dive in step by step!
Why is Psychological Research Important?Psychological research helps us understand human behaviour and mental processes. It provides evidence for improving treatments, policies, and everyday practices. Conducting research requires careful planning and ethical considerations to ensure valid and reliable results.
Key Research PrinciplesResearch in psychology must be objective, empirical (based on data), and replicable (can be repeated with similar results). These principles ensure findings are trustworthy and contribute to practical applications.
