We must be careful when choosing a topic, considering both its innovation and its practical significance. Have both, that's the best. You can also choose the current hot issues.
When designing graduation thesis, if it involves experimental design, whether it is intervention research or observation research, its feasibility should be considered.
In addition, the sampling method and sample size of the experiment should be calculated well. Think again and again. If all the calculations here are wrong, then the experimental results must be inaccurate. Not convincing.
When doing experiments, it should be convenient and feasible to ensure the accuracy of experimental results to the greatest extent.
There are a lot of resources now, so when we design our graduation thesis, we must read more literature. No matter what kind of topic it is, it will be helpful to look at other people's research in this field.
Look at the information more, and you will naturally be able to check the leaks and fill the gaps. Whether it is the design of the experiment or the elaboration of the paper. Can be more comprehensive.
