Depending upon whether your course is of a scientific or mathematical nature, meaning that you are likely to be dealing with experiments providing you with definitive results and quantitative analysis; or a more theoretical nature, meaning that your research will mainly be qualitative; your hypothesis will be proven or disproven throughout the course of your dissertation.
The first step in creating your dissertation proposal should be planning its structure.
You do not necessarily require a ‘conclusion’, but it might be a good idea to round off your dissertation proposal with a reminder of your reasons for choosing the topic, the type of research you will be carrying out and your expected outcomes.
For example - ‘I have chosen to investigate the relationship between ___ and ___ since I believe that proving a positive correlation would have serious implications for ___, and that carrying out further qualitative research in this area will be integral to improving understanding.
Overall, a dissertation proposal is essential in preparing you for the writing process and will actually serve to make beginning your dissertation decidedly less frightening.
Plus, it is not set in stone and will probably be subject to much change during the entire process.
Producing a coherent dissertation proposal helps you to communicate with your supervisor the aims and objectives for your research, and the methods you intend to use in making an assessment of your topic.
Your supervisor may then present you with a critical evaluation of your proposal, highlighting areas in which they foresee difficulty, ethical concerns, or lack of transparency.
Whether you're writing an undergraduate or postgraduate proposal, it's vital you check your course and institution requirements prior to submission, since the word count and format can vary between universities.
According to usual practice, you'll likely be assigned a supervisor from your subject area, who'll guide you throughout the dissertation writing process.
