The reason is that every research paper is unique and different in its sense.
The only difference you have to understand is that you must restate your thesis in the first statement of your conclusion.
You may also do it in the last part of your entire research paper.
It will give your work the exact direction needed because the introduction of a research paper mainly focuses on the purpose and objectives of the paper and that’s what you need to present in your summary.
But do not use the only introduction to write the summary.
A research paper may be longer than a typical essay.
Anyway you will have to know how to write a conclusions for a research papers as well.So, it usually requires more than 1 page (275 words).But you should stick to the requested list of writing style (MLA, Chicago, etc.) the most frequent paper world format used in conclusions for a research papers is APA.You cannot give your summary the required finishing touch if you don’t read every section of the paper.In the chapters where the writer has used different methods or explained procedural working or processes of a certain phenomenon, you need to understand it to a degree from where you would be able to analyse how the writer was able to conclude results coming out of such methodology.Concluding a research paper seems to be a less tiresome job than actually creating a research paper.Students assume that it may not consume their enough time and efforts if they are assigned to create a summary of an already existing research paper. It is unmistakably true that the process of research paper writing is a lot rigorous type of work to do.But you cannot afford to take conclusion a paper non-seriously.It surely needs some homework and skills before you get your hands on a research paper written by someone else and summarising its theme and central points in one paper.Therefore, one should have a better understanding of how to evaluate and examine a particular research paper and summarise it according to its content specifically.It is a common habit found among the young and immature students that they assume the ‘abstract’ of the paper to be serving as the summary for them.
