Tennis Match Statistics

The dataset contains a total of 20,562 data sets. The ball speed of the two players ranges from 98 km\/h to 226 km\/h, with an average ball speed of 166.72 km\/h. As shown in Table 1, the movement distances of the two players are generally similar, but the maximum value of Player 1 is higher than that of Player 2. For serve directions, they are divided into five categories: 1 (body serve), 2 (body\/middle), 3 (body\/crosscourt), 4 (middle), 5 (crosscourt); for the situation of serving close to the boundary line, \close\ is recorded as 1, and \not close\ is recorded as 2. Since the latter two variables are categorical variables, their mean and variance are not listed in Table 1.
