形容毕业论文难的句子英语

well, i haven't gone into this issue thoroughly. i'd appreciate it very much if you could give me some instructions.

1. 描述有哪些limitation？

2. 描述这些limitation为什么存在，即为什么无法被克服？

明明知道有这些limitation，为什么不在写论文的时候就去克服呢？是否有一些客观原因让你确实无法做到？这部分也是你justify your choice的时候！

3.描述这些limitation会带来的什么影响？

这部分非常重要！因为有limitation没关系，关键要说清楚这些limitation对于你的研究的影响有多大。读完后要让读者觉得，这些limitation虽然存在，但是没有大到影响整个研究可信度的程度！

4.描述这些limitation会引出哪些future research？

常见limitation总结：

-样本量不够大（sample size is too small）

-有效数据不够多（lack of reliable data）

-样本可能有bias，普适性（generalisability)较低（biased sampling profile,比如全部都是用的student sampling）

-缺乏对此课题的已有研究（lack of existing research on the topic）

-实验设计本身带来的局限性（如self-reported data,可能会出现bias；二手数据，可能会数据过时）

-实验仪器的问题（limitations in the technology/instruments used to collect your data）

-时间问题（limited time,导致带来一些不完美）
