Definitions

n
n is the number of employees.
Average
The average is calculated by summing all values and dividing by the total number of values. This is also known as arithmetical average and mean.

The following statistical terms are determined by ordering the data values in ascending order:

Median
The median value is the midpoint of all values. It is the point for which 50% of values are below and 50% of values are above.
Q1
The first quartile (Q1) is the point for which 25% of values are below and 75% of values are above.
Q3
The third quartile (Q3) is the point for which 75% of values are below and 25% of values are above.
P5
The 5th percentile (P5) is determined by dividing the distribution of values into 100 equal parts and then identifying the point where 5% of the values are below and 95% of values are above.
P95
The 95th percentile (P95) is determined by dividing the distribution of values into 100 equal parts and then identifying the point where 95% of the values are below and 5% of values are above.

Example: values ranging from 1 to 20 inclusive

The tables in this report were prepared using SAS. There are many methods used to determine the median, quartiles and percentiles. Where a data point falls between two values, the method used in this report takes the mean of those two values.

Base Salary
Base Salary describes the full-time equivalent annualised salary paid to an employee. It includes salary sacrifice amounts (including pre–tax employee superannuation contributions made by salary sacrifice) and excludes bonuses and other benefits.
Total Remuneration Package (TRP)
TRP is defined as being Base Salary plus the value of any benefits including superannuation and motor vehicles.
Total Remuneration Package (TRP) calculation
TRP = Base Salary + (plus)
  Agency superannuation contribution
  Motor vehicle cost/EVS
  Cash in lieu of motor vehicle
  Motor vehicle parking
  Other benefits
  Other supplementary payments not otherwise described
Total Reward (TR)
TR is defined as being TRP plus bonuses.
Total Rewards (TR) calculation
TR = TRP + (plus)
  Actual performance bonus paid in previous 12 months
  Actual retention bonus payments paid in previous 12 months
  Productivity bonus
  Sign on bonuses
  Group or whole of agency performance bonus and allowances
Total Rewards plus Allowances (TR+A) calculation
TR + A = TR + (plus)
  Additional duties/responsibilities allowances
  Qualifications and/or skills based allowances
  Market related allowances, specific job
  Market related allowances, specific individual
  Superannuation allowances
  Income maintenance allowance
  Hours of duty allowances
  Expense allowances
  Geographic/locality allowances
  Disability allowances
  Health and lifestyle allowances
  Individual performance related allowances
  Annual leave loading

How to read a box plot:

The size of the squares in relation to each other also reveals how evenly distributed the data values are. For example, looking at the Agency bar in the plot above, the lower two squares (P5 to Median) are shorter than the two above (Median to P95). This indicates that there is a smaller range in values for the bottom 45% compared to the top 45%. The APS bar illustrates that the APS data values appear to be more evenly distributed as all four squares appear to be of similar length.
