不同高爾夫開球木桿桿身對擊球距離的影響分析

目的：探討2018年市售的88款高爾夫開球木桿桿身，其在桿身重量及價格之差異對擊球距離的影響分析。方法：本研究以程度相當於單差點的男子業餘高爾夫球友或女子職業高爾夫選手的試打球手（揮桿速度快）為測試者，其針對市售的88款高爾夫開球木桿桿身在擊球距離的表現進行試打；承上，再依桿身重量及價格之差異對距離表現結果去進行比較。並採皮爾森積差相關分析進行考驗。分析得到下列結果：（一）桿身重量的平均數為59.69克，其最大值為71克；最小值為29.5克，兩者相差了41.5克，約2.4倍之多。至於桿身重量與撃球距離之間的關聯為0.259，顯著性為0.015，兩者達到顯著的正相關，意謂著桿身越重距離越好。（二）桿身價錢方面其最大值為120,000日幣；最小值為5,600日幣，兩者相差了114,400日幣，高達21.4倍之多。惟桿身價格與撃球距離之間的關聯未達到顯著的正相關（.153）。承上，意謂著越貴的桿身在開球擊球距離的表現並未更遠。惟藉由描述統計可看出，兼顧輕量及穩定度的桿身最能取得撃球距離上的優勢，但缺點是它所費不貲價格昂貴。

Objective: To analyze the impact of the difference between the weight and price of the 88 golf driver shafts in 2018 on the driving distance. Method: This study was conducted by the top men's professional golfer (swing speed fast) against the performance of the 88 golf driver shafts in the market. Compare the difference between shaft weight and price on the performance of distance. And the Pearson Product-Moment Correlation analysis was tested. The analysis obtained the following results: (1) The average weight of the shaft was 59.69 g, and its maximum value was 71 g; the minimum value was 29.5 g, which was 41.5 g, about 2.4 times. As for the correlation between the weight of the shaft and the distance of the ball is 0.259 and the significance is 0.015, the two achieve a significant positive correlation, which means that the heavier the distance, the better. (2) The maximum price of the shaft is 120,000 yen; the minimum is 5,600 yen, which is a difference of 114,400 yen, up to 21.4 times. However, the correlation between the shaft price and the driving distance did not reach a significant positive correlation (.153). According to the above, it means that the more expensive the shaft is not farther away from the driving distance. However, it can be seen from the descriptive statistics that the shaft with both light weight and stability can best obtain the advantage of the driving distance, but the disadvantage is that it is expensive.
