Box Plot of Lotto Draw Results Over Time
The chart below displays the statistical distribution, spread, or variability of winning Lotto numbers from Feb. 24, 2025 to Aug. 16, 2025 , across 75 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 Illinois Lotto
The Illinois Lotto has undergone several format changes below since its launch to enhance gameplay:
| Period | Format | Extra Shot |
|---|---|---|
| February 19, 1983 | 6/40 | None |
| May 13, 1984 | 6/44 | None |
| April 15, 1990 | 6/54 | None |
| October 28, 1998 | 6/52 | None |

How Illinois Lotto Format Changes Affect Your Number Strategy.
The 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 frequently in the 6/50 format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 6/52 and 6/54 format.
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.
