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 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.

How US Lucky 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 frequently in the 5/40 format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 5/43 or 5/48 formats.
Therefore, for a 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.
