本研究針對2008北京奧運壘球賽之打擊數據，以統計軟體算出各隊打擊數據指標之平均數、眾數、中數，三種統計方式，再進一步與該隊勝率與總得分進行相關分析，最後針對其異同加以比較討論，希望能提供國內壘球相關人員做為參考。本研究採用記錄分析法，利用SPSS 17.0統計軟體描述性統計功能計算打擊數據之平均數、中數、眾數，再以Pearson積差相關分析各變項與勝率、得分之相關性，所得之結論如下：一、以平均數所計算之打擊率、長打率、上壘率、被四壞保送次數與球隊勝率及總得分皆達顯著相關，打數則與球隊勝率達到顯著相關。二、以中數所計算之打擊率、長打率、上壘率與球隊勝率及總得分皆達顯著相關，打數則與球隊勝率有顯著相關。三、以眾數所計算之打擊率、長打率、上壘率與球隊勝率及總得分皆達顯著相關，打數則與球隊勝率有顯著相關。四、比較上述研究結果，除被四壞保送次數之研究結果不同，只有在以平均數計算時才出現顯著性，其餘變項之研究結果均相同。

This study based on the database of baseball game from Peking Olympic Game which is held in year 2008. The data of hit which used statistic program to obtain data of mean, mode and median results. From this results, analysis that conjunction with data of ”percentage of game won” and ”total score gain from game” of each team. This study used Record-Analysis Method, descriptive statistic function of statistics software called SPSS 17.0 to calculate mean, median and mode data of batting data. After obtain those result, use Pearson correlation coefficient analysis to obtain data of relationship between the variables and percentage of game won” as well as the variables and wining score” respectively. Following are the results of this study: 1. Calculation by using mean obtains that batting average, slugging average, on base percentage and base on ball are deeply connected with Team's percentage of game won and total score team gain; numbers of batting, then, deeply connected with Team's percentage of game won. 2. Calculation by using median obtains that batting average, slugging average, are deeply connected with Team's percentage of game won and total score team gain; numbers of batting, then, deeply connected with Team's percentage of game won. 3. Calculation by using mode obtains that batting average, slugging average, on base percentage and base on ball are deeply connected with team's percentage of game won and total score team gain; numbers of batting, then, deeply connected with team's percentage of game won. 4. Comparing the results mentioned above, beside base on balls has different results.
