close-to-significantp = 0.056
Although only statistical significance was observed for ranked ( p = 0.013) and top 50 players ( p = 0.031) born in 1999, and when all the age groups were pooled together ( p = 0.002) along with a close-to-significant ( p = 0.056) difference identified for top 50 players born in 2001, this needs to be interpreted in relation to the small sample size of this study, particularly for the top 10 player category.
