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 Mar. 4, 2025 to Nov. 18, 2025 . The possible range values are divided into bins or categories. In this case, the bins span intervals such as 4-12 up to 67-69, 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 49-57 with 21 occurrences, suggesting that combinations with this level of spread are the most common. In contrast, the least frequent range is 13-21 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 Mega Millions Lottery

Since its inception in 1996, Mega Millions has undergone several changes in its number pool format, particularly in the main number set and the Mega Ball. Initially launched as “The Big Game,” the format started with selecting 5 numbers from a pool of 50 and 1 Mega Ball from a pool of 25 and expanded its number matrix several times in 2005, 2013, and 2017. in April 2025, the format was revised again, maintaining the 5/70 for the main numbers but slightly reducing the Mega Ball pool from 1/25 to 1/24. These adjustments over time have been aimed at balancing jackpot size, odds of winning, and overall game excitement.

Period Format Mega Ball
September 6, 1996 – Launch as “The Big Game” 5 of 50 1 of 25
May 17, 2002 – Rebranded “The Big Game Mega Millions” 5 of 52 1 of 52
October 2002 – 2005 5 of 56 1 of 46
October 18–22, 2013 5 of 75  1 of 15
October 28–31, 2017 5 of 70 1 of 25
April 8, 2025 5 of 70 1 of 24

How US Mega Millions 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 5/50 format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 5/75 or 5/70 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.
