In lottery number analysis, the Interquartile Range (IQR) measures the spread of the middle 50% of drawn numbers. It is also used in showing how tightly or loosely the central values cluster, helping reveal typical spacing behavior in lotto results.

Histogram of Number Clustering

The histogram of number clustering measures the typical spacing between consecutive numbers in lotto draws. Each bin represents a range of average gaps, showing whether numbers tend to cluster closely together or spread evenly across the draw. This histogram helps analysts detect patterns in number spacing, complementing other perspectives such as sums and ranges.

The histogram of average gaps between consecutive numbers in lotto draws reveals that the most frequent gap interval is 7-8 with 18 occurrences, suggesting a strong clustering in this interval. In contrast, the least frequent gap interval is 1-2 with 0 occurrences, showing it is rarely observed. This indicates a noticeable concentration of draws around certain gap intervals. Overall, the distribution shows clustering around specific gap intervals, indicating that draws tend to gravitate toward these values.
