    去英国留学,不少学生在统计学硕士学位课程学习时,会遇到很多的习题作业,当然也会有相应的essay作业,这里留学海外论文辅导给大家分享英国大学统计学essay范文。

    介绍:

    本文旨在分析两个变量之间的相关性,即大学生工作时间和睡眠时间之间的关系,并研究性别是否对此相关性产生影响。

    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:

    本研究随机选择了100名大学生进行样本调查。参与者被要求填写问卷,记录他们的性别、每周工作小时数和每晚获得的睡眠小时数。采用皮尔逊相关系数检验分析调查得到的数据,以确定两个变量之间的相关程度。T检验也被用来研究男女之间在相关性方面是否存在显著差异。

    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.

    结果:

    分析显示大学生工作时间和获得睡眠时间之间存在中等负相关(r=-0.42, p<0.05)。这表明随着工作时间的增加,获得的睡眠时间减少。然而,相关性在女性中没有显著意义(r=-0.28, p>0.05),但在男性中具有统计学意义(r=-0.59, p<0.05)。这表明男性的工作时间和睡眠时间之间存在更强的负相关。

    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.

    讨论:

    这项研究的结果表明,大学生的工作时间和获得的睡眠时间之间存在显著相关性。这与之前的研究一致,表明长时间工作会导致睡眠不足(Buxton等,2012)。然而,相关性只在男性中具有统计学意义,这表明性别可能在这种关系中起到了作用。社会文化因素,如对工作和家庭责任的态度,可能影响男女平衡工作和睡眠的方式。需要进一步研究来验证这个假设。

    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.

    结论:

    总之,本研究表明大学生的工作时间和获得的睡眠时间之间存在中等负相关性。这种相关性在男性中具有统计学意义,但在女性中没有显著性,表明性别可能会影响工作和睡眠之间的关系。这些发现对需要平衡学业、工作和其他责任的大学生具有重要意义。建议学生采取措施优化他们的睡眠模式,如减少工作时数或改善睡眠卫生习惯。

    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.
