When might a median be a more valid statistic than a mean? - are both equally impacted by outliers?
Median is better to use when there is a limited amount of data, or when there are many outliers, whereas mean is better to use when scores in a set of data cluster closely around a central score and when there are no outliers.
Both are not equally impacted by outliers.
Most of the time, go for the mean. It is tested the most in psych and median is rarely used. Same with mode, being rarely used.
Question 38, on psyched 2018 states; ‘Tyson has started drinking alcohol heavily to deal with the stress he is under’ and then asks what 4P factor his heavy drinking relates to – I assumed it was ‘precipitating’ as that would correlate directly to substance use however the answer guide says ‘perpetuating’ – is this because his drinking is a result of precipitating risk being stress – or as such are the factors in the table non binary? ‘Excessive alcohol consumption is an avoidance coping strategy that is likely to inhibit his recovery from the stressors that he is facing’
Alcohol use seems to be perpetuating in this circumstance as it is occurring after his stress. If it was occurring before, it may be considered as precipitating his stress. Similar to poor sleep, substance use can be precipitating or perpetuating based on the scenario.
• Can implicit memories be stored in the cerebral cortex? – specifically the primary motor cortex? Or is it more correct to say that they are all consolidated and stored in the cerebellum? Are there exceptions to this?
Implicit memories are
not stored ANYWHERE in the cerebral cortex according to VCE psychology. Implicit procedural memories are stored in the neural pathways between the cerebellum and basal ganglia. For VCAA, just saying they are stored in the cerebellum should be enough. Classically conditioned motor reflexes are also stored here. Classical conditioning involving the conditioning of fear (i.e. Little Albert) is stored in the amygdala. The amygdala is responsible for the consolidation and storage of implicit emotional classically conditioned memories.
What is the difference between content limitations as a psychological measure of consciousness in comparison to day dreaming? – is daydreaming a result of poor content limitations?
Reduced content limitations are a characteristic of daydreaming, an ASC.
it shall be in my best interests that I avoid this thread forever or at least until examiners report comes out
