Opponent coverage changes the estimate

04 Methods

Sample and definitions

These comparisons describe the games in the supplied file. They cannot establish why score margins changed.

Source and sample

The competition supplied NCAA Women's Basketball Data Files 2026. This analysis uses games.parquet. Its data dictionary names ESPN / SportsDataverse as the data pipeline.

Of 114,705 unique game IDs, 114,588 have final, unequal, positive scores. The source labels 111,965 of those games as regular season (season_type = 2). Some March conference tournament games carry that label. Limiting the analysis to November-February leaves 101,730 games across 21 seasons.

Measures

Margin is the absolute difference between final scores, including overtime. "20+" includes games decided by exactly 20. The source's conference_competition field identifies conference games.

The comparisons pool 2005-06 through 2007-08 and 2023-24 through 2025-26. Each percentage divides qualifying games by all included games in that period. Seasons are labeled by ending year. The 2020-21 season has fewer recorded games and appears in the annual chart.

Limits of the data

The file has not been audited for completeness. The November-February cutoff also excludes some regular-season games in March. Team coverage, schedules, conference membership and scoring can change across seasons. The charts do not isolate the effect of any one factor.

The optional filter keeps a game when both teams played at least five recorded conference games that season. It is a check on opponent coverage, not an NCAA division label. The team chart uses all qualifying 2025-26 games.
