This chart shows how winning lotto numbers have varied over time. Each box highlights the middle range of results, with the line inside marking the median number for that draw period. The chart makes it easy to spot shifts in number spread and check the overall randomness of the draws.
Box Plot of Lotto Draw Results Over Time
The chart below displays the statistical distribution, spread, or variability of winning lotto numbers across multiple draws over time. Each box represents the middle 50% of numbers (from the first quartile to the third quartile), while the line inside the box marks the median winning number for that period. The “whiskers” extend to the minimum and maximum numbers drawn, and any points outside these whiskers indicate unusually low or high results relative to other draws. By tracking how the quartiles and range shift over time, the chart provides insight into the variability and spread of winning numbers, which can be used to visually assess the randomness and consistency of lotto draws.
Quartile and Range Characteristics
The table below presents the statistical characteristics of each lotto draw with range, skewness, and spread. The range measures the gap between the lowest and highest numbers. Skewness indicates whether the numbers are concentrated toward the lower or higher end of the pool, helping to identify directional bias in the draw. The IQR (Interquartile Range) shows how widely the numbers are spread or distributed within the middle 50% of results, and clustering highlights whether certain numbers tend to appear close together within the same draw. Together, these metrics provide a deeper view of the draw’s randomness and number distribution patterns.

Format Changes in Australia's Set For Life Lottery
Since its inception in August 2015, Australia's Set for Life lottery has undergone significant changes to enhance gameplay and increase winning opportunities.
| Period | Format | Supplementary Nos. |
|---|---|---|
| August 2015 - March 22, 2020 | 8 numbers from a pool of 37 (8/37) | 2 numbers from the same pool. |
| March 23, 2020 - Present | 7 numbers from a pool of 44 (7/44) | 2 number from the same pool |
Since its launch in August 2015, the Australian Set for Life lottery has undergone notable changes aimed at improving gameplay and enhancing player experience. Initially, players were required to select 8 numbers from a pool of 1 to 37. Each draw produced 8 winning numbers and 2 supplementary numbers.
On March 23, 2020, significant revisions were introduced. The format changed to selecting 7 numbers from a larger pool of 1 to 44, and each draw now produces 7 winning numbers and 2 supplementary numbers. The number of prize divisions expanded to eight, with players now able to win a prize by matching as few as 3 main numbers and 1 supplementary number. These changes also improved the overall odds of winning a prize, shifting from 1 in 59 to 1 in 50. Overall, the modifications were designed to create more frequent and appealing prize opportunities for participants.
How Australia's Set for Life Lotto Format Changes Affect Your Number Strategy.
These format changes have a direct impact on statistical analysis. Mixing frequency data across different formats is not advisable because each version of the game has a different number pool and probability structure.
For example, a number that appeared less frequently in the 8/37 format may have done so due to lower individual draw probability, but that same frequency can be misleading in the 7/44 formats.
Therefore, for meaningful analysis, it’s essential to treat each format as its own distinct dataset. Analyzing trends or frequencies should be restricted to results from within the same format period, especially if the goal is to inform number selection in the current game structure.
