Mean, Standard Deviation (STDEV), and Range Trend

The chart below presents the statistical trends of Lotto Texas lotto combinations from Jun. 14, 2025 to Dec. 6, 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 Lotto Texas

Since it started on November 7, 1992, the game has undergone several format changes:

Period Format Bonus Ball
Nov 7, 1992 6 numbers out of 54 None.
May 7, 2003 5 numbers out of 54 1
Apr 22, 2006 6 numbers out of 54 None/Dropped

Initially introduced as a traditional 6/54 matrix game. In May 2003, the game shifted to a bonus-ball format, where players selected five (5) main numbers plus one (1) bonus number, significantly altering the odds and prize structure. However, this format was short-lived; by April 22, 2006, Lotto Texas reverted to its original 6/54 format, eliminating the bonus ball and simplifying the game again.

How Lotto Texas 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 5/54 format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 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.
