This chart displays the statistical trends of consecutive draws, showing how the mean, standard deviation, and range of numbers drawn vary over time. This illustrate the variability and distribution patterns inherent in random lottery results.

Mean, Standard Deviation (STDEV), and Range Trend
The chart below presents the statistical trends of Lotto lotto combinations from Nov. 30, 2024 to Aug. 16, 2025 , covering 75 draws by tracking the mean, standard deviation, and range.
The Mean line indicates the average drawn number per draw, the Standard Deviation (STDEV) line shows how widely spread the numbers in each draw are from their respective mean, and the Range line, calculated as the difference between the highest and lowest number in each draw, shows the gap between the highest and lowest numbers drawn.
Together, these statistics and their trends offer a clearer picture of the variability inherent in lotto draws, though they do not imply predictability, as true lottery systems are designed to be random. It helps to observe whether the statistical properties of the drawn numbers exhibit any pattern, volatility, or clustering over time.
Format Changes in New York Lotto
The current format of New York Lotto is 6/59, which means, the players select 6 numbers from a pool of 1 to 59. During the draw, 6 main numbers and 1 bonus number are drawn from the same pool of numbers. But when New York Lotto was introduced in 1978, the format was different:
| Period | Format | Bouns Ball |
|---|---|---|
| November 8, 1978 | 6/40 | 1 from the same pool of remaining numbers |
| May 22, 1983 | 6/44 | 1 from the same pool of remaining numbers |
| Nov 26, 1986 | 6/54 | 1 from the same pool of remaining numbers |
| Nov 27, 1999 | 6/59 | 1 from the same pool of remaining numbers |
How New York 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 6/40 format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 6/54 and 6/59 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.
