A VCE Psychology student is conducting a study on the effects of sleep deprivation on cognitive performance. After collecting data, they notice that several participants reported significantly lower cognitive scores than expected. Upon further investigation, the student discovers that the room where some participants completed the cognitive tasks was unusually noisy due to nearby construction.
Which of the following best describes the most appropriate way to address this issue when analysing the data?
Exclude all data collected from participants who completed the tasks in the noisy room, as this introduces a systematic error.
Compare the cognitive scores of participants who completed the tasks in the noisy room to those who completed them in a quiet room, to identify the effect of the noise as a confounding variable.
Average the cognitive scores of all participants, regardless of the testing environment, to minimise the impact of individual differences.
Adjust the cognitive scores of participants who completed the tasks in the noisy room by adding a fixed value to compensate for the noise, assuming the noise affected all participants equally.

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.
Students undertake a student-designed scientific investigation in either Unit 3 or Unit 4, or across both Units 3 and 4, related to mental processes and mental wellbeing. The investigation involves the generation of primary quantitative data. Students apply key science skills to develop and test a research question, gather and analyse data, and communicate findings in a structured scientific poster. A logbook is maintained for authentication and assessment purposes.
