A VCE Psychology student hypothesises that listening to calming music during study sessions will improve students’ self-reported focus. To investigate this, they recruit 40 Year 12 students and randomly assign them to either a music group (listening to calming music during study) or a control group (studying in silence). After two weeks, all participants complete a standardised focus questionnaire. Discuss how the student could use measures of central tendency and measures of dispersion to analyse the data collected in this investigation and what conclusions could be drawn from these analyses.

In this unit students explore the demand for sleep and the influences of sleep on mental wellbeing. They consider how changes to a person’s sleep-wake cycle can affect psychological functioning. Students explore the concept of mental wellbeing, including social and emotional wellbeing as a multidimensional and holistic framework. They apply a biopsychosocial approach to specific phobia, exploring how biological, psychological and social factors are involved in its development and management. A student-designed scientific investigation involving the generation of primary data related to mental processes and mental wellbeing is undertaken in either Unit 3 or Unit 4 or across both Units 3 and 4, and is assessed in Outcome 3 of this unit.
