You will need it to be succinct, specific, descriptive, and representative of the research you have done.
There is likely to be a required format for the title page in your discipline, so you need to check what that is.
Any imbalance in space devoted to different sections of content will become apparent.
This is a useful check on whether amalgamation of sections, or creation of further sections or sub-sections is needed.
This may be one of the shortest sections of your thesis or dissertation, but it is worthwhile taking great care to write it well.
Essentially, the Abstract is a succinct summary of the research.You will need to check which style of reporting is preferred in your field.For example a scientific dissertation would probably have very clear separation between the results and the discussion of those results; whereas a social science dissertation might have an overall chapter called Findings, bringing the results and their discussion together.If you used particular equipment, processes, or materials, you will need to be clear and precise in how you describe them.You must give enough detail for another researcher to replicate your study.The Abstract is an important element of the thesis, and will become a document in its own right if the thesis is registered within any database.The examiners will therefore assess your Abstract both as part of your thesis, and as a potentially independent document.The good news is that you have already started writing if you have written any of the following in relation to this study: In each case the object of the writing was to communicate to yourself, your supervisors, or to others, something about your work.In writing your dissertation you will draw on some of this earlier writing to produce a longer and more comprehensive account.You may also find the following Study Guides helpful: “The research is going well, so the writing should be straightforward - I can leave it until later”.“I know I’m not good at writing so I keep putting it off”.
