[USER (data scientist)]: Thank you, Tapilot. We aim to examine any significant trends or shifts in the correlation between court surfaces and player performance within the atp_tennis dataset over time. To achieve this, we will conduct a Time Series Analysis, encompassing line charts, trend analysis, and statistical test results. In addition, I would appreciate an answer to the following question: On which surfaces do players tend to exhibit higher win/loss ratios compared to others? What were the correlation coefficients, and what do they suggest about the relationship between surface types and player performance?
A. clay, relatively weak, no strong
B. hard, relatively weak, no strong
C. grass, relatively strong, strong
D. hard, relatively strong, strong
E. clay, relatively strong, strong
F. None of above
