The Range is also one of the basic statistics often used to study past draws. It is the difference between the highest and lowest number in each draw which shows how spread out lotto numbers are within combinations.

Histogram of Range Values

Histogram of Ranges

A histogram of ranges is used as a statistical representation that shows how often different spread values occur in lotto draws. It also highlights whether draws are typically made up of closely clustered numbers, broadly spread numbers, or something in between. The range of a combination is determined by subtracting the smallest number from the largest number in a draw.

The histogram of ranges below covers 75 draws from May. 14, 2025 to Nov. 5, 2025 . The possible range values are divided into bins or categories. In this case, the bins span intervals such as 4-11 up to 60-68, with each bin representing a continuous span of range outcomes.

This categorization is important because the range can vary significantly from draw to draw, and grouping outcomes into bins allows you to identify patterns more clearly. For instance, a concentration of draws in smaller ranges would suggest that numbers often appear close together, whereas higher frequencies in larger ranges indicate that numbers are more widely spread across the lotto field.

The most frequent range is 52-59 with 20 occurrences, suggesting that combinations with this level of spread are the most common. In contrast, the least frequent range is 4-11 with 0 occurrences, indicating that draws falling into this spread are relatively rare. This points to a clear clustering of draws around certain range values. Overall, the distribution of ranges tends to cluster in certain spread intervals, showing that draws are more likely to fall within these specific ranges.

Format Changes in US Powerball Lottery

Since its inception on April 22, 1992, the U.S. Powerball has undergone several significant changes in format and structure. At launch, Powerball became the first lottery game to use a dual-drum format—drawing five white balls from one set and one red Powerball from another—designed to create more prize tiers. Initially, players selected 5 numbers from 45 white balls and 1 from 45 Powerballs.

In November 1997, the format changed to 5/49 + 1/42. This was followed by another change in October 2002, expanding the white ball pool to 53 while keeping the Powerball at 42. By August 2005, the white balls increased again to 55. A major change occurred in January 2009, with the matrix becoming 5/59 + 1/39. Around this time, Florida joined the game, and the drawings were moved there.

One of the most notable changes came in January 2012 when the Powerball pool was reduced to 35, while the white balls remained at 59. Another significant format change was introduced in October 2015, adjusting the matrix to 5/69 + 1/26. This increased the odds of winning smaller prizes while making the jackpot harder to win, with overall odds shifting to approximately 1 in 292 million.

Period Format Powerball
April 1992 5 of 45 1 of 45
November 1997 5 of 49 1 of 42
October 2002 5 of 53 1 of 42
August 2005 5 of 55 1 of 42
January 2009 5 of 59 1 of 39
January 2012 5 of 59 1 of 35
October 2015 5 of 69 1 of 26

How US Powerball 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 5/49 format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 5/69 formats.

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.
