去英國留學(xué)，不少學(xué)生在統(tǒng)計(jì)學(xué)碩士學(xué)位課程學(xué)習(xí)時，會遇到很多的習(xí)題作業(yè)，當(dāng)然也會有相應(yīng)的essay作業(yè)，這里留學(xué)海外論文輔導(dǎo)給大家分享英國大學(xué)統(tǒng)計(jì)學(xué)essay范文。

    介紹：

    本文旨在分析兩個變量之間的相關(guān)性，即大學(xué)生工作時間和睡眠時間之間的關(guān)系，并研究性別是否對此相關(guān)性產(chǎn)生影響。

    Introduction

    The aim of this essay is to analyse the correlation between two variables, namely the number of hours worked and the amount of sleep obtained by university students. It will also investigate whether gender has any effect on this correlation.

    方法：

    本研究隨機(jī)選擇了100名大學(xué)生進(jìn)行樣本調(diào)查。參與者被要求填寫問卷，記錄他們的性別、每周工作小時數(shù)和每晚獲得的睡眠小時數(shù)。采用皮爾遜相關(guān)系數(shù)檢驗(yàn)分析調(diào)查得到的數(shù)據(jù)，以確定兩個變量之間的相關(guān)程度。T檢驗(yàn)也被用來研究男女之間在相關(guān)性方面是否存在顯著差異。

    Methodology

    A sample of 100 university students was randomly selected for this study. The participants were asked to complete a questionnaire that recorded their gender, the number of hours they worked per week and the number of hours of sleep they obtained each night. Data collected from the survey was analysed using the Pearson correlation coefficient test to determine the level of correlation between the two variables. A t-test was also conducted to investigate if there was any significant difference in the correlation between males and females.

    結(jié)果：

    分析顯示大學(xué)生工作時間和獲得睡眠時間之間存在中等負(fù)相關(guān)（r=-0.42, p<0.05）。這表明隨著工作時間的增加，獲得的睡眠時間減少。然而，相關(guān)性在女性中沒有顯著意義（r=-0.28, p>0.05），但在男性中具有統(tǒng)計(jì)學(xué)意義（r=-0.59, p<0.05）。這表明男性的工作時間和睡眠時間之間存在更強(qiáng)的負(fù)相關(guān)。

    Results

    The analysis revealed a moderate negative correlation between the number of hours worked and the amount of sleep obtained by students (r=-0.42, p<0.05). This suggests that as the number of hours worked increases, the amount of sleep obtained decreases. However, the correlation was not found to be statistically significant for females (r=-0.28, p>0.05), but was statistically significant for males (r=-0.59, p<0.05). This indicates that there is a stronger negative correlation between hours worked and sleep obtained for males than for females.

    討論：

    這項(xiàng)研究的結(jié)果表明，大學(xué)生的工作時間和獲得的睡眠時間之間存在顯著相關(guān)性。這與之前的研究一致，表明長時間工作會導(dǎo)致睡眠不足（Buxton等，2012）。然而，相關(guān)性只在男性中具有統(tǒng)計(jì)學(xué)意義，這表明性別可能在這種關(guān)系中起到了作用。社會文化因素，如對工作和家庭責(zé)任的態(tài)度，可能影響男女平衡工作和睡眠的方式。需要進(jìn)一步研究來驗(yàn)證這個假設(shè)。

    Discussion

    The results of this study suggest that there is a significant correlation between the number of hours worked and the amount of sleep obtained by university students. This is consistent with previous research indicating that working long hours can contribute to sleep deprivation (Buxton et al., 2012). However, the fact that the correlation was only statistically significant for male students indicates that gender may play a role in this relationship. It is possible that socio-cultural factors, such as attitudes towards work and family responsibilities, may influence the way in which males and females balance work and sleep. Further research is needed to investigate this hypothesis.

    結(jié)論：

    總之，本研究表明大學(xué)生的工作時間和獲得的睡眠時間之間存在中等負(fù)相關(guān)性。這種相關(guān)性在男性中具有統(tǒng)計(jì)學(xué)意義，但在女性中沒有顯著性，表明性別可能會影響工作和睡眠之間的關(guān)系。這些發(fā)現(xiàn)對需要平衡學(xué)業(yè)、工作和其他責(zé)任的大學(xué)生具有重要意義。建議學(xué)生采取措施優(yōu)化他們的睡眠模式，如減少工作時數(shù)或改善睡眠衛(wèi)生習(xí)慣。

    Conclusion

    In conclusion, this study has shown that there is a moderate negative correlation between the number of hours worked and the amount of sleep obtained by university students. This correlation was found to be statistically significant for male students but not for females, suggesting that gender may influence the relationship between work and sleep. These findings have important implications for university students who need to balance their academic commitments with work and other responsibilities. It is recommended that students take steps to optimise their sleep patterns, such as reducing the number of hours worked or improving sleep hygiene practices.
