• The calculated mean $1487.312, the median is
measured to be $1476.5
• shows that the data is roughly symmetrically
distributed as the difference between the
mean and median is $10.812
• Since the standard deviation shows little
variation we can gather that the data is closely
bunched around the mean value
• The findings can only be used as an
approximation to gather a holistic view of
earning distribution within Australia. Discrete
data for each individual within each state and
territory would allow for a more accurate
representation of earnings. 

GRAPHICAL SUMMARY
• The graph visually describes the average
weekly income of a person over 15
compared across the various Australian
states
• This allows a quick and rough overview of
the income disparity across the states.
• Contrasts the level of income in each
state, with ACT having the highest
average income, and Tasmania having
the lowest.
