n is the number of employees.
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:
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.
The first quartile (Q1) is the point for which 25% of values are below and 75% of values are above.
The third quartile (Q3) is the point for which 75% of values are below and 25% of values are above.
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.
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 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.
TRP = Base Salary
- + 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.
TR = TRP
- + 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)
TR+A is defined as being TR plus allowances.
TR+A = TR
- + 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.
