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 Thunderball lotto combinations from Jul. 23, 2025 to Nov. 29, 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.
Statistical Analysis
The Mean remains relatively stable, with no clear long-term shift towards higher or lower averages. Overall, the mean values fluctuate significantly throughout the dataset, reflecting the randomness expected in lottery outcomes.
The Standard Deviation (STDEV) shows the values remain relatively stable, showing a consistent mix of tightly grouped and more spread-out draws. In general, the standard deviation values fluctuate significantly across the dataset.
The Range remains generally stable, with fluctuations that balance out over time. Overall, the range values fluctuate significantly across the dataset, highlighting variations in the spread of drawn numbers.
Format Changes in UK Thunderball
Since its launch in June 1999, the UK Thunderball lottery has undergone several key format changes aimed at enhancing the game and increasing player excitement. These adjustments have expanded the number selection pool.
| Period | Format | Thunderball |
|---|---|---|
| June 1999 | 5 numbers out of 34 | 1 number out of 14 |
| May 9, 2010 | 5 numbers out of 39 | 1 number out of 14 |
Throughout these changes, the Thunderball number has always been drawn from its own pool of 14 numbers, separate from the main numbers, preserving the structure that has defined the game since its creation.
How Thunderball 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 frequently in the 5/34 number format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 5/39 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.
