### Chi-Square Goodness-of-Fit Tests  
From Table 5, it is evident that for set plays, a statistically significant difference was observed only in terms of match status. Specifically, final attempts from set plays were less frequent when the match score was tied (\(p\) = 0.017) compared to situations in which one of the two teams was leading. In contrast, no statistically significant differences were found in terms of time period (\(p\) = 0.075) or match location (\(p\) = 0.496).  
Table 5 indicates that for open-play final attempts, no statistically significant differences were observed in terms of time period (\(p\) = 0.232) or match location (\(p\) = 0.265). However, significant differences were found in several other variables. First, the final attempts were more frequent when the score was not tied (\(p\) = 0.014). Second, attempts were more common when there was no initial pressure from the opponent (\(p\) < 0.001). Third, attempts were more frequent when there was initial penetration (\(p\) = 0.014). Furthermore, organized attacks were associated with a higher frequency of final attempts than counter-attacks (\(p\) = 0.006).  
Moreover, statistically significant differences were found in the initial sector of the attack (\(p\) < 0.001). For this indicator, since there were more than two categories, post hoc

tests were conducted to examine which categories showed differences. Owing to multiple (six) comparisons, the adjusted significance level was set at 0.05/6 = 0.0083. Table 6 presents the results of the post hoc tests, which show that final attempts starting from the offensive sector are fewer than those starting from the defensive (\(p\) < 0.001), pre-defensive (\(p\) < 0.001), and pre-offensive sectors (\(p\) < 0.001).
