[USER (data scientist)]: We aim to examine the influence of different court surfaces on the performance of players in the ATP tennis dataset, categorized into top-ranked, mid-ranked, and low-ranked groups. This will be achieved through a Stratified Analysis, incorporating charts and statistical tests (p-values) to compare performance across these ranking groups and court surfaces. The top-ranked players are those ranked between 0 and 50, mid-ranked players are between 50 and 200, while any ranking beyond 200 is considered low-ranked. Given this information, could you please clarify which group of players appears to be most significantly affected by the type of court surface?
A. top-ranked
B. mid-ranked
C. low-ranked
D. unranked
E. None of above
